Specifications
■ HOW TO OPEN THE FRONT COVER
Position your finger on the hook at the top of front cover
and pull.
POINTS OF CAUTION
■ POWER INPUT RATINGS
• Operational range & power consumption: Check the power rating for the unit on the specification label.
AC rating: Rating ±10%, 50/60 ±2 Hz, approx. 2VA
DC rating: Rating ±10%, approx. 2W
■ UNPLUGGING THE UNIT
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ WIRING
• Do not install cables (power supply, input and output)
close to noise sources (relay drive cable, high frequency
line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
The shape of base socket may be different
for some models.
INSTALLATION
Detach the yellow clamps located at the top and bottom of
the unit to separate the body from the base socket.
■ DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bottom. Position the upper hook
at the rear side of base socket
on the DIN rail and push in
the lower. When removing
the socket, push down the
DIN rail adaptor utilizing a
minus screwdriver and pull.
■ WALL MOUNTING
Refer to “EXTERNAL DIMENSIONS.”

Shape and size of the base socket
are slightly different with various
socket types.
■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

CHECKING
MAINTENANCE
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the described specifications shown below.
Regular calibration procedure is explained below:
OUTPUT
LORD REQUIREMENTS
Open Collector 50V DC @50mA max. (resistive load)
■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 5%,
25%, 50%, 75% and 100% input signal. Check that the output signal for the respective input signal remains within
accuracy described in the data sheet. When the output is
out of tolerance, recalibrate the unit according to the “ADJUSTMENT PROCEDURE” explained earlier.
AC/DC switch
100V AC @200mA max. (cos ø = 1)
150V DC @200mA max. (resistive load)
Voltage pulse
1kΩ min. for 5V
2.4kΩ min. for 12V
4.8kΩ min. for 24V
Relay contact
30V DC @200mA max. (resistive load)
120V AC @200mA max. (cos ø = 1)
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
M-System to choose appropriate models.
Output pulse width: The pulse width is factory set to a
value, between 5 µsec. and 0.8 sec., at which the duty ratio becomes 50% of the maximum frequency of a specified
range. If this value lies outside of the adjustable range,
either maximum or minimum selectable value will be
used.
Check the acceptable pulse width of the connected instrument.
ADJUSTMENT PROCEDURE
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any calibration.
For matching the signal to a receiving instrument or in case
of regular calibration, adjust the output as explained in the
following.
■ HOW TO CALIBRATE THE OUTPUT SIGNAL
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 10 minutes.
1) ZERO: Apply 5% input and adjust output to 5%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 5% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).
