CHASSIS AND POWER SUPPLY
1.1
Introduction: Safety Considerations
WARNING 1: The power supply/signal conditioner
should not be opened by anyone other than qualified
service personnel. This product is intended for use by
qualified personnel who recognize shock hazards and
are familiar with the safety precautions required to
avoid injury.
WARNING 2: This equipment is designed with user
safety in mind; however, the protection provided by the
equipment may be impaired if the equipment is used in
a manner not specified by PCB Piezotronics, Inc.
Caution 1: Cables can kill your equipment. High
voltage electrostatic discharge can damage electrical
devices. Similar to a capacitor, a cable can hold a
charge caused by triboelectric transfer, such as that
which occurs in the following:
•
•
•
•
Lying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person.
The solution for product safety: 1) Connect the cables
only with the AC power off. 2) Temporarily “short” the
end of the cable before attaching it to any signal input or
output.
Caution 2: ESD considerations should be made prior
to performing any internal adjustments on the
equipment. Any piece of electronic equipment is
vulnerable to ESD when opened for adjustments.
Internal adjustments should therefore be done ONLY in
an ESD-safe work area. Many products have ESD
protection, but the level of protection may be exceeded
by extremely high voltage.
WARNING SYMBOLS AND TERMS
The following symbols and terms may be found on the
equipment described in this manual.
This symbol on the unit indicates that the user should
refer to the operating instructions located in the manual.
This symbol on the unit indicates that high
voltage may be present. Use standard safety
precautions to avoid personal contact with this voltage.
This symbol indicates safety, earth ground.
The WARNING heading used in this manual explains
dangers that might result in personal injury or death.
Always read the associated information very carefully
before performing the indicated procedure.
The Caution heading used in this manual explains
hazards that could damage the instrument.
EQUIPMENT RATINGS
For complete specifications, please refer to the enclosed
Specification Sheet. This equipment operates at 104°F
(40°C), in an environment having 93% relative
humidity. Its frequency range is 50/60 Hz. Operation
of this unit is limited to environments having an altitude
of less than 2 000 meters. The pollution degree for
operation of the Model 440 is Two (2), meaning that
normally, only non-conductive pollution occurs. The
over voltage category is II, indicating the transient
voltage levels that may be tolerated by the equipment.
The Model 441A101 requires 100 to 240 VAC with 1.3
amps to operate. It gets its power via an AC line cord
that plugs into the receptacle on the rear panel. (The
Model 441A102 – DC supply does not use this
receptacle.)
Two rear panel fuses, located below switch in the AC
receptacle, protect the power line inputs of the
instrument. The fuse type is a T 1.6A, L 250 V. To
change the fuse, disconnect the power cord. Find the
slot just above the power switch and pull forward to
open the door that exposes the fuse drawers. Pull the
individual drawer forward and insert a new fuse. See

DESCRIPTION
The PCB Modular Signal Conditioning System is a
flexible, compact means of coordinating and
customizing the signal conditioning needs of vibration,
pressure, or force sensing instrumentation. At its most
basic level, the system consists of a rectangular chassis
with a single-slot power supply on the right side of the
chassis and one module (customer specified). This
power supply is either AC or battery power, depending
on customer requirements. It should be noted, however,
that the AC and DC power supplies are separate units,
having differing part numbers. See Section 1.2.3 and
1.2.4 for a more detailed description of the power
supplies.
1.2.1
Chassis (Model 441A42, 441A43,
441A35, 441A39, 441A45, 441A49)
Models 441A45 and 441A49 are “slave” racks designed
to be controlled by a “master” rack (441A33, 441A35,
441A38, 441A39). These racks do not have an RS-232
connector, but only two RS-485 connectors, which may
be connected to either a master, or another slave in a
daisy chain fashion. At least one master must be in the
system if it is desired to use computer control.
Located on the rear panel of these racks is a cooling fan,
which normally is on. If it is desired to turn off the fan
in order to reduce acoustical noise, a jumper “J2”
located on the motherboard must be removed. In order
to access this jumper, the rear panel must be taken off.
The fan may now be disabled via a command from the
host computer controlling the master. The fan should be
disabled for as short a period as possible to ensure
continuous cooling. Contact the factory for more details.
1.2.2
AC Power Supply (Model 441A101)
The chassis configuration varies, ranging from two slots
to nine; one of these slots (extreme right) is reserved for
the power supply. Situated on the rear panel behind the
power supply slot is a power entry module that includes
an on/off switch, fuses, and a power filter for use with
the AC power supply only. See Figure 1.
The Model 441A01 is a single-slot, CE marked, AC-line
power supply designed to fit only the extreme right slot
of the PCB Series 440 Modular chassis. It supplies a
maximum of 45 watts of power and may be used to
operate single or multiple signal conditioning modules
housed in the two-, three-, or nine-wide standard chassis
and optional auxiliary chassis.
Euro card-style plug-in modules occupy the remaining
slots. For a complete listing of available modules, see
Section 1.4.
The power unit supplies a maximum of 45
watts of power. Please note that while this
unit is rated for a maximum wattage of 45, CE
requirements mandate that it be used only up
to 30 watts.
The standard chassis is constructed of molded plastic
with molded ventilation slots. The 19-inch rackmounted unit is constructed of metal.
Wattage calculations are found on the Specification
Sheet for the individual module. To determine power
capability of your particular set-up, use the following
procedure:
MODULAR SIGNAL CONDITIONING SYSTEM GENERAL OPERATION MANUAL

1.
Add all the powers for all modules. CE mandates
that these totals must be < 30 watts.
1.2.3
DC Power Supply (Model 441A102)
Model 441A102 is a single width, CE marked,
rechargeable DC battery power supply designed to fit
only the extreme right slot of the PCB Series Modular
chassis. It supplies a maximum of 30 watt/hrs and may
be used to operate single or multiple signal conditioning
modules housed in the two-, three-, or nine-wide
standard chassis and optional auxiliary chassis.

optional Model 488A09 AC power adaptor. Both these
external power sources plug into the EXT DC jack
located on the front panel. Refer attached operation
guide for the Model 441A102 in appendix A.
1.3
MAINTENANCE AND REPAIR
Aside from battery replacement on units so equipped,
no maintenance is required for this modular unit, other
than wiping the exterior of the chassis with a soft cloth
when dusty. If you experience difficulty with your
particular unit, contact the factory for assistance.
Because of the sophisticated nature of PCB
instrumentation, field repair is typically not
recommended and voids the warranty. If factory
service is required, return the instrument to PCB. A free
quotation is provided prior to servicing.
To expedite the repair process, contact a PCB Customer
Service Representative for a Return Materials
Authorization (RMA) number prior to sending
equipment to the factory.
Please have pertinent
information available, such as model and serial
numbers, application information, what instruments are
connected to the equipment, and so forth. Also, to
insure efficient service, be sure to include a brief written
description of the problem. International customers
should return equipment to a local distributor, or contact

Introduction: Safety Considerations
WARNING 1: The power supply/signal conditioner
should not be opened by anyone other than qualified
service personnel. This product is intended for use by
qualified personnel who recognize shock hazards and
are familiar with the safety precautions required to
avoid injury.
WARNING 2: This equipment is designed with user
safety in mind; however, the protection provided by the
equipment may be impaired if the equipment is used in
a manner not specified by PCB Piezotronics, Inc.
Caution 1: Cables can kill your equipment. High
voltage electrostatic discharge can damage electrical
devices. Similar to a capacitor, a cable can hold a
charge caused by triboelectric transfer, such as that
which occurs in the following:
•
•
•
•
Lying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person.
The solution for product safety: 1) Connect the cables
only with the AC power off. 2) Temporarily “short” the
end of the cable before attaching it to any signal input or
output.
Caution 2: ESD considerations should be made prior
to performing any internal adjustments on the
equipment. Any piece of electronic equipment is
vulnerable to ESD when opened for adjustments.
Internal adjustments should therefore be done ONLY in
an ESD-safe work area. Many products have ESD
protection, but the level of protection may be exceeded
by extremely high voltage.

equipment described in this manual.
This symbol on the unit indicates that the user should
refer to the operating instructions located in the manual.
This symbol on the unit indicates that high
voltage may be present. Use standard safety
precautions to avoid personal contact with this voltage.
This symbol indicates safety, earth ground.
The WARNING heading used in this manual explains
dangers that might result in personal injury or death.
Always read the associated information very carefully
before performing the indicated procedure.
The Caution heading used in this manual explains
hazards that could damage the instrument.
EQUIPMENT RATINGS
For complete specifications, please refer to the enclosed
Specification Sheet. This equipment operates at 104°F
(40°C), in an environment having 93% relative
humidity. Its frequency range is 50/60 Hz. Operation
of this unit is limited to environments having an altitude
of less than 2 000 meters. The pollution degree for
operation of the Model 440 is Two (2), meaning that
normally, only non-conductive pollution occurs. The
over voltage category is II, indicating the transient
voltage levels that may be tolerated by the equipment.
The Model 441A101 requires 100 to 240 VAC with 1.3
amps to operate. It gets its power via an AC line cord
that plugs into the receptacle on the rear panel. (The
Model 441A102 – DC supply does not use this
receptacle.)
Two rear panel fuses, located below switch in the AC
receptacle, protect the power line inputs of the
instrument. The fuse type is a T 1.6A, L 250 V. To
change the fuse, disconnect the power cord. Find the
slot just above the power switch and pull forward to
open the door that exposes the fuse drawers. Pull the
individual drawer forward and insert a new fuse. See

DESCRIPTION
The PCB Modular Signal Conditioning System is a
flexible, compact means of coordinating and
customizing the signal conditioning needs of vibration,
pressure, or force sensing instrumentation. At its most
basic level, the system consists of a rectangular chassis
with a single-slot power supply on the right side of the
chassis and one module (customer specified). This
power supply is either AC or battery power, depending
on customer requirements. It should be noted, however,
that the AC and DC power supplies are separate units,
having differing part numbers. See Section 1.2.3 and
1.2.4 for a more detailed description of the power
supplies.
1.2.1
Chassis (Model 441A42, 441A43,
441A35, 441A39, 441A45, 441A49)
Models 441A45 and 441A49 are “slave” racks designed
to be controlled by a “master” rack (441A33, 441A35,
441A38, 441A39). These racks do not have an RS-232
connector, but only two RS-485 connectors, which may
be connected to either a master, or another slave in a
daisy chain fashion. At least one master must be in the
system if it is desired to use computer control.
Located on the rear panel of these racks is a cooling fan,
which normally is on. If it is desired to turn off the fan
in order to reduce acoustical noise, a jumper “J2”
located on the motherboard must be removed. In order
to access this jumper, the rear panel must be taken off.
The fan may now be disabled via a command from the
host computer controlling the master. The fan should be
disabled for as short a period as possible to ensure
continuous cooling. Contact the factory for more details.
1.2.2
AC Power Supply (Model 441A101)
The chassis configuration varies, ranging from two slots
to nine; one of these slots (extreme right) is reserved for
the power supply. Situated on the rear panel behind the
power supply slot is a power entry module that includes
an on/off switch, fuses, and a power filter for use with
the AC power supply only. See Figure 1.
The Model 441A01 is a single-slot, CE marked, AC-line
power supply designed to fit only the extreme right slot
of the PCB Series 440 Modular chassis. It supplies a
maximum of 45 watts of power and may be used to
operate single or multiple signal conditioning modules
housed in the two-, three-, or nine-wide standard chassis
and optional auxiliary chassis.
Euro card-style plug-in modules occupy the remaining
slots. For a complete listing of available modules, see
Section 1.4.
The power unit supplies a maximum of 45
watts of power. Please note that while this
unit is rated for a maximum wattage of 45, CE
requirements mandate that it be used only up
to 30 watts.
The standard chassis is constructed of molded plastic
with molded ventilation slots. The 19-inch rackmounted unit is constructed of metal.
Wattage calculations are found on the Specification
Sheet for the individual module. To determine power
capability of your particular set-up, use the following
procedure:
MODULAR SIGNAL CONDITIONING SYSTEM GENERAL OPERATION MANUAL

1.
Add all the powers for all modules. CE mandates
that these totals must be < 30 watts.
1.2.3
DC Power Supply (Model 441A102)
Model 441A102 is a single width, CE marked,
rechargeable DC battery power supply designed to fit
only the extreme right slot of the PCB Series Modular
chassis. It supplies a maximum of 30 watt/hrs and may
be used to operate single or multiple signal conditioning
modules housed in the two-, three-, or nine-wide
standard chassis and optional auxiliary chassis.

Features:
The main feature of the 441A102 is Portable Power. 30 Watt/Hrs are available from the internal
battery. Data Protection is assured with the low battery indicator specified to come on at exactly nine
tenths of the battery life, giving adequate warning of Power shutdown. When the battery needs
charging, simply use the included 488A08 to quickly recharge the battery in about an hour.
Low noise operation is an added benefit of the 441A102 because of its’ Ultra High Technology DC-toDC converters.
Any PCB Modular Series Products can be utilized in a mobile test system with a very simplified and
reliable connection to the vehicles cigarette lighter socket, with the included 017A22 (3 Amp fuse
protected) DC Power cord.
Specifications:
See Specification Sheet for Model 441A102.
Operation:
The 441A102 can be used to power up to 30 watts of PCB modular series units. Simply slide it into the
enclosure, in the power supply slot, and tighten up the two mounting screws. Turn on the power switch
and it’s ready to go! The estimated battery life can be calculated by dividing 30 by the total number of
watts of all the units being used together. See each units Spec. Sheet for the number of watts to use in
your calculation.
The 441A102 will automatically turn off when the battery has reached complete exhaustion. The power
will remain “OFF” until the Power switch is turned off and back on again. Please review the attached
specification sheet for the Model 441A102.
Note” (1) Model 488A08 and Model 017A22 are supplied accessories. (2) The Model 488A09 AC

MODEL 442B104 FOUR-CHANNEL ICP SENSOR SIGNAL CONDITIONER
2
5.0 Model 442B104
The module 442B104 features an AC-coupled output
and incremental gain of x1, x10, and x100 per channel.
The 442B104 also features the ability to plug in
optionally available Low Pass filters in each channel.
The filters to be used are the Model 477A series.
Several standard cut offs are available. (contact PCB for
further information)
If you wish to learn more about sensors with built-in
microelectronic circuitry, known as ICP sensors, consult
PCB’s “General Operating Guide for use with
Piezoelectric ICP Accelerometers,” a brochure outlining the technical specifics associated with
piezoelectric sensors. Topics covered include charge
versus voltage mode systems, sensor time constants,
effect of discharge time constant on low-frequency
response, and power requirements.
Connect each sensor to the SENSOR jack of the Model
442B104 using the appropriate cable.
Connect the readout to the OUTPUT jack using a BNCto-BNC cable. Wait for 1-3 minutes to allow the system
to settle out before taking data.
Note: Many types of connector adaptors are available
from PCB to simplify difficult installation situations.
Consult the factory for details.
Input faults are indicated by individual channel LEDs.
With an ICP sensor connected to the input jack, no
5.1 DESCRIPTION
The Model 442B104 supplies a sensor excitation
voltage of +24-volt DC and a constant sensor excitation
current adjustable from 0.5 to 20 mA to four ICP
sensors simultaneously. Refer to Figure 5.1 (Model
442B104 front panel).
The output signal is AC coupled and is compatible with
standard readout instruments. The coupling time
constant in the AC mode is greater than 10 seconds and
is independent of output load.
The front panel contains four BNC Sensor input jacks
(SENSOR) and four BNC output jacks (OUTPUT).
Individual channel menu buttons set the gain at x1, x10,
or x100. The ICP constant current adjust access hole is
also located on the front panel
Four LED fault monitors, one per channel, are located
on the front panel to provide the user a means to check
circuit continuity and operation. Thes LEDs indicate the
gain selected for each channel. Input faults, such as
overload, open, and short, are indicated by the LEDs.
5.2 OPERATION
Turn the power on using the rocker switch located on
the back panel. When first powered on, the gain LEDs
will flash three times.
Figure 5.1 Model 442B104 Front Panel
MODEL 442B104 FOUR-CHANNEL ICP SENSOR SIGNAL CONDITIONER

input fault lights are illuminated. However, if the sensor
or cable is open, the LED is a solid red. If the cable or
sensor is shorted, the LED blinks. Finally, if the input
signal exceeds ± 10 volts, the LED enlightens until the
overload is removed.
Optionally available, PCB Model 401A04 ICP Sensor
Simulator consists of a unity gain, non-inverting,
impedance-converting voltage amplifier similar to those
found in many ICP sensors. When used in conjunction
with a signal generator, the electrical characteristics of
long cables can be easily determined.
5.3
To set the constant current adjustment locate the
constant current adjust hole on the front panel of the
Model 442B104. Hook a 0-30mA meter to the sensor
input of any channel. Put a small screwdriver through
the hole, and carefully turn the pot clockwise to increase
current or counterclockwise to decrease current. The
current level may be read on the meter. Note that this
sets the current on all four channels simultaneously to
the same value.
Coupling
A coupling capacitor AC couples the system internally
with a greater-than-10-second coupling time constant
(TC). This gives a low-frequency response as follows:
1%
5%
30% (-3 dB)
down at
down at
down at
.11 Hz
.05 Hz
.016 Hz
NOTE: This table applies to a sensor system where the
discharge TC of the sensor is greater than 100 seconds.
Shorter TC sensors shorten the overall system TC
accordingly.
This coupling is desirable for standard operation since
long-term thermal drifting of long TC sensors is
nullified by the internal AC coupling. The DC offset at
the output is, at the maximum, +/-50 mV.
5.4
Setting the Constant Current
The Model 442B104 is normally supplied with the
constant-current output set at four mA nominal. This is
adequate for most laboratory and field applications.
Special situations, such as driving extra long (beyond
1000 ft) cables having high frequency or fast rise-time
pulses, may require increasing the sensor drive current
above four mA.
CAUTION
To avoid permanent damage to the sensor, DO NOT
EXCEED 20 mA.
When driving fast rise-time pulses over long lines,
system performance can be optimized by “tuning” the
drive current to the line. Find the best current setting for
the particular set of physical parameters (line length,
line termination, or pulse rise time) established by the
sensor. The optimum current setting is best determined
by experimentation with your particular test setup. A
good rule of thumb is to use the lowest current
consistent with satisfactory results to minimize sensor
self-heating and noise.
5.5
Installing the Filters
To install the filters, first unscrew and slide out the
Module 442B104. Locate the filter socket fil101, fil102,
fil103 and fil104 located behind the BNC connectors on
the board. Plug the optional series 477A into these
sockets. Located above these sockets is 1 selectable
shunts per filter fil1, fil2, fil3 and fil4. Move the shunt
from pin 1 and 2 to cover pin 2 and 3. Pin 1 is
uncovered in filter mode. Contact PCB for assistance if
necessary.
