FeaturesMulti-input

ModbusTotal 18 types of input can be chosen from thermocouple (10 types),
RTD (2 types), Direct current (2 types) and DC voltage (4 types).
For direct current input, a built-in 50 Ω shunt resistor or externally mounted
50 Ω shunt resistor can be selected.

Serial communication (C5 option) protocol comprises Shinko protocol andModbus protocol. For Modbus protocol, RTU mode or ASCII mode isselectable by keypad. This indicator can be connected to the Modbus
compatible instruments without using a communication converter.

Alarm Output (3 points) is Provided as Standard

Standard Dust-proof/Drip-proof (for front panel only)

Alarm output (3 points) is available as standard.
Alarm type and status Energized/De-energized can be easily
switched by keypad. (Factory default: No alarm action, Energized)

IP66 structure means the indicator can be used even in harshenvironment exposed to dust and water splashes.

Standard Transmission Output

Safety Standards

Converting the input value to analog signal every 125 ms, outputs
the value in direct current.
4 to 20 mA DC output is a standard feature.
