+12V Sensor Excitation

Isolate between the sensor output and the excitation supply.

+24V Two-wire Transmitter Excitation

For use with a smart transmitter (e.g. HART), choose ‘DC voltage input’

and ‘two-wire transmitter excitation’ when ordering, and then connect

as shown below.

Non-smart transmitters are also usable.

Unless the sensor output does not force minus direction

such as 0 to 5 V or 4 to 20 mA, the configuration as shown

below is possible. It is not available except measurement

range 1 to 5 V, ±5 V, 4 to 20 mA or 0 to 20 mA.

*1. Resistor module (model: REM2-250) is provided separately.

Attach the REM2 to the terminals 3 – 4 as shown below.
