Feature:
Programmable for various input signals,
   measuring range
Configurable without external Loop Power Connected.
Suitable to Mount Inside a KN box.
Input :
Resistance thermometer (Pt100)
Thermocouple (J,K,T,E,B,R,S,N,C)
Voltage/Current transmitter ( V/mA not selectable,
   request by order. )

Output :
2-wire loop-power technology, 4 to 20 mA or 20 to 4 mA    analog output.
High accuracy in total ambient temperature range.
Fault signal on sensor break presettable.

   
 
The IST-H DIN rail transmitter is user configurable with The software and interface cable URC-1020 or handheld programmer.The is user-friendly software. The latest release version can be download free from website. Interface cable consist of interface converter and USB plug. It can be purchased separately from The supplier. During configuration the transmitter can work alone without connecting to a power source.
