● Analog output
This wiring is used to transmit the 4-20mA DC signal to a recorder or other device. The load
resistance including wiring resistance should be 550 Ω or less
Cable specifications:
Each CH requires 2 cores for this wiring.
Select the number of cores according to the number of contacts to be used.
Wiring instructions:
(1) Use M3 threaded terminal screws on the converter. The tightening torque is 0.6 N•m.
Use crimp terminals compatible with these screws to terminate the cable.
(2) Do not wire with reversed polarity. Wire carefully to avoid mistaking the “+” and “-” polarity.
● RS-485 communication (digital communication: available when -R is selected)
RS-485 (Modbus RTU) can be selected as an option for this product.
Use shielded cables to prevent malfunction due to external noise and to avoid radiation noise
from the IR800G/IR810G from affecting other equipment.

10 TERM For connecting a terminating
resistor (110 Ω)
Use multi-core shielded cables with stranded (twisted pair) cores.
Connect the shield to terminal 2 on terminal block 2.
Terminate the signal with a built-in signal terminator (110 Ω resistance) according to the
communication environment.
Connect terminals 8 and 10 of terminal block 2 when terminating.
Use M3 terminal screws. The tightening torque is 0.6 N•m.
