GFK-0367E
The block may be powered by 115 VAC or 10 to 30 VDC. Auxiliary DC
power can be used when the main power to the block is supplied by 115
VAC. Both 115 VAC and DC power may be supplied simultaneously
and if the 115 VAC source fails, the block will continue to operate on the
DC backup power. Any DC source that can provide an output in the
range of 10 VDC to 30 VDC can be used. The source must meet the
specifications listed in the table on page 1 of this datasheet. With both
AC and DC power applied, block power will be taken from the AC input
as long as the DC voltage is less than 20 volts.
Using this Datasheet _________________________
This datasheet summarizes information about block installation,
configuration, and diagnostics.
Your primary reference should be the Discrete and Analog Blocks
User’s Manual. It includes detailed instructions for block installation
and configuration. For additional information about systems and
communications, including bus specifications, refer to the I/O
System and Communications Manual.
The block is configured for the application to function in one of the
following ways:
as four 16-bit counters. Each of the four may independently count
either up or down. This block configuration is referred to as “Type
A”.
as two 24-bit counters. Each may independently operate in
Up/Down, Pulse/Direction, or A Quad B mode. This configuration is
referred to as “Type B”.
as one 24-bit differential counter, which can operate in Up/Down,
Pulse/Direction, or A Quad B mode. This is referred to as “Type C”
configuration.
Compatibility ________________________________
This block requires Hand-held Monitor version 3.5 (IC66*HHM501D)
or later. HHM version 4.0 or later is required to use all the features
described in this datasheet.
For the IC600 series PLC, bus controller version IC66*CBB902G or
IC66*CBB903G or later is required for blocks assigned to I/O
references, to assure data coherency. For blocks assigned to
register memory, earlier versions of bus controllers IC66*CBB902
and IC66*CBB903 can be used. Bus controllers IC66*CBB900 and
IC66*CBB901 cannot be used with a High-speed Counter.
The block’s outputs can be programmed to turn on or off when the
accumulated count reaches appropriate Preset values, as shown by the
following example.
Block Operation _____________________________
The High-speed counter block accepts 12 input signals, and
provides 4 output signals for counter operations.

Each output has a response delay of 1ms maximum; repeatability is
0.5ms or less. The commanded state of each output is shown by an
individual LED on the block. Outputs may be forced on or off using the
Hand-held Monitor, or by command from the application program. This
is useful during installation and checkout.
Output 4
Input 12
Each output has built-in electronic protection against short circuits. If an
output is commanded to turn on and the current through the switch
exceeds 4 Amps for a period of 1 millisecond, the block automatically
shuts off the switch and generates a FAILED SWITCH diagnostic.
+5 Volts
Oscillator
Short circuit protection protects the block if loads are 4 Amps or more.
Each output on the block can source a maximum of 0.5 Amps.
Switching of loads between 0.5 Amps and 4 Amps is shown below.
Inputs can be used for count signals, direction, disable, edgesensitive strobe, and other inputs.
Outputs can be used to drive indicating lights, solenoids, relays, and
other devices. Each output has a response delay of 1ms maximum;
repeatability is 0.5ms or less. Each output circuit provides built-in
protection against power surges caused by wiring errors.

Installation Instructions _______________________
Inserting an Electronics Assembly
Carefully inspect all shipping containers for damage. If any
equipment is damaged, notify the delivery service immediately. Save
the damaged shipping container for inspection by the delivery
service. After unpacking the equipment, record all serial numbers.
Save the shipping containers and packing material in case it is
necessary to transport or ship any part of the system.
1.
Align the Electronics Assembly in the guides and push down firmly.
Caution
Do not exert excessive force; it may damage the block.
2.
If unusual resistance is met, remove the Electronics Assembly. If
power is applied to the block, DO NOT TOUCH THE CONNECTOR
PINS! Inspect the Terminal Assembly, connector receptacle, and
connector edge board (on the Electronics Assembly). Be sure the
keying matches. Remove any obstacles and reinsert the
Electronics Assembly. Pay close attention to the alignment of the
guide pins.
3.
Secure the Electronics Assembly with the screws on the top and
bottom of the Terminal Assembly.
Block Mounting
Genius I/O blocks are considered "open equipment" and therefore
must be installed within a protective enclosure. They should be
located in an area that is clean and free of airborne contaminants.
There should be adequate cooling airflow.
The block can be mounted right side up, or upside down. Leave at
least 2 inches of space between blocks. Mount the block by drilling
two screw or bolt holes for 8-32 hardware. Position the block so that
the notches in the upper and lower flanges line up with the mounting
holes. Mount the block using 8-32 screws. Use star washers to
provide ground integrity.
Note: If the Electronics Assembly has been removed from a block for
some length of time, contaminants may have built up on the exposed
connector pins. After the block is reassembled, these contaminants
could affect the accuracy of measurements. When reassembling the
block, push the Electronics Assembly in and out a few times to assure a
fresh mating surface.
Grounding
The block’s mounting screws must not be used as the only means
of grounding the block. Connect the green ground screw on the
block to a reliable ground system using a short wire lead, minimum
size AWG #12 (avg 3.3mm2 in cross-section).
LEDs _______________________________________
The block's Unit OK and I/O Enabled LEDs show its operating status:
Warning
Unit OK
If mounting screws do not make good ground connection
and the ground screw is not connected to a reliable ground,
the block is not grounded. Electrical shock hazard exists.
Death or personal injury may result.

from 5 volts to 30 volts DC, depending on the output level needed. The
maximum steady-state current supplied by any output is 0.5 amp.
Do not overtorque the terminal screws. Recommended torque for all
terminals is 6 in/lb (.678 N/M).
For both AC and DC block power, the 5V+ terminal (terminal 14) can be
used to drive any load, including output loads, that falls within its
capacity of 4.75 to 5.25 volts at 200 mA.
Serial Bus Wiring
Caution
Terminals 1 to 4 are for the serial bus. These terminals accept one
AWG #12 wire (avg 3.3mm2 cross-section) or two AWG #14 wires
(each avg 2.1mm2 in cross-section). The minimum recommended
wire size is AWG #22 (avg .36mm2 in cross-section).
Do not apply loads greater than 200mA to the +5V output
(terminal 14). Doing so may damage the block.
Terminal
Terminals 1 - 4 can also accommodate spade or ring terminals up to
0.27 inch (6.85mm) wide with a minimum opening for a #6 screw,
and up to 0.20 inch (5.1mm) depth from the screw center to the back
barrier. Be sure unshielded wire ends are not longer than 2 inches
(5 cm).
Using one of the cable types recommended in the System and
Communications User’s Manual, connect the serial bus to terminals
1- 4.

Connect the bus cables to the BSM. Connect either of the BSM
pigtail wires to terminals 7. Connect the other to terminal 8.
Field Wiring _________________________________
Terminals 5 to 46 are for field devices. Each terminal accepts one
AWG #14 wire (avg 2.1mm2 in cross section), two AWG #14
(2.1mm2 cross section) solid wires, or two AWG #16 (each avg
1.3mm2 in cross section) stranded wires. Minimum recommended
wire size is AWG #22 (avg .36mm2 in cross section).
The table below shows terminal assignments for field wiring to each
block type (A, B, and C). For all block types, connect differential
inputs to the terminals as shown. Connect the + input to the +
terminal, and the - input to the - terminal. For single-ended signals
(abbreviated ”se” in the table) make a connection to the + diff
terminal only. Leave the - terminal unconnected.
Terminal 36, labelled OSC, is a CMOS/TTL compatible totempole
output. Do not use an external pullup resistor for this terminal.
Terminals O1 through O4 are for outputs that will be driven by a DC
power supply wired to VL+ (terminal 15). This voltage may vary

GFK-0367E
Any 10 to 30 VDC source can be used. With both AC and DC power
applied, block power will be taken from the AC input as long as the DC
voltage is less than 20 volts. Above 20 volts, block power is drawn from
the DC input, even if AC power is still applied. Connect the AC source to
the Hot and Neutral terminals. Connect the DC backup to DC+ and DC-.
The following illustration shows connections for AC block power with DC
backup, and output power from the block’s 5-volt output (see Output
Power Connections ).
Wiring for Block Power _______________________
The block may be powered by 115VAC (at 60mA typical) or 10VDC
to 30VDC (at 250mA typical). If the block is powered by an AC
source, DC power can also be applied as a backup.
AC Block Power
For an AC power source, connect the HOT lead to the terminal.
Connect neutral to the N terminal. If Class 1 Division 2 conditions
must be met for Factory Mutual, install an external 250-volt 1/8 Amp
slow-blow fuse in series with the H terminal.
DC Block Power
If the block will be powered by a 10VDC to 30VDC source, connect the +
side of the source to the DC+ terminal (terminal 13). Connect the - side
to any DC- terminal (terminals 42 through 46). The following illustration
shows connections for DC block power with a separate external DC
source for the outputs (see Output Power Connections).

The block’s four outputs (O1 through O4) require a 5VDC to 30VDC
source. If logic-level signals are needed for the outputs and their total
load will not be more than 200mA, the block’s +5V output can be used
as the power source. Output power can also come from the same DC
source used for block power, or a separate DC power source.

Connecting VL+
AC Block Power with DC Backup
If no block outputs (O1 through O4) will be used, jumper the block’s +5V

Configuration _______________________________
First, the block must be configured with a Hand-held Monitor to:
Enter its Device Number (serial bus address).
Enter its counter type (A, B, or C).
Enter its Reference Number (required only for IC600 and IC550
series PLCs only).
Note: If a block is configured offline, it must be properly grounded
and have a 75 Ohm resistor installed across its Serial 1 and Serial 2
terminals. See the High-speed Counter User’s Manual for
instructions. The rest of the features can be configured either using
a Hand-held Monitor, or by sending a Write Configuration datagram
to the block from the host.
Note: If the counter is operating at a count rate of 150KHz or higher,
run-time configuration changes should be made using a Hand-held
Monitor.
