■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
INSTALLATION
POINTS OF CAUTION
Loosen the fixing screw at the front of the unit in order to
separate the body from the
base socket.
■ POWER INPUT RATING & OPERATIONAL RANGE
•Locate the power input rating marked on the product and
confirm its operational range as indicated below:
100 – 240V AC rating: 85 – 264V,
47 – 66 Hz, approx. 3 – 5VA
24V DC rating: 24V ±10%, approx. 3W
11 – 27V DC rating: 11 – 27V, approx. 3W
110V DC rating: 85 – 150V, approx. 3W
■ GENERAL PRECAUTIONS
•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 with sufficient ventilation.
•Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•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.
•Be sure that the ventilation slits are not covered with cables, etc.
■ 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.”
■ 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.
■ 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.
•With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to endure it without breakdown, however, it may shorten appropriate life duration.

TERMINAL CONNECTIONS
MAINTENANCE
Connect the unit as in the diagram below or refer to the connection diagram on the side of the unit.
When an input resistor is provided with the module, attach
it together with input wiring to the input screw terminals.
Regular calibration procedure is explained below:

■ CALIBRATION
Warm up the unit for at least 10 minutes. Apply -100%,
-50%, 0%, +50%, +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.

The section enclosed by broken line is only with 2nd output option.
*Input shunt resistor attached for current input.
CHECKING
1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
3) Input: Check that the input signal is within -100 – +100%
of the full-scale.
4)Output: Check that the load resistance meets the described specifications.
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 0% input and adjust output to 0%.
2) SPAN: Apply 100% input and adjust output to 100%.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above procedure 1) – 3).
5) Go through the same procedure for the Output 2.
