Microprocessor Based Programmable lsolated Transmitter
A Programmable & user-friendly transmitter , IST-D was bom.

 

Feature:
PC programmable for various input signals,
   measuring range
Configurable without external Loop Power Connected.

Input :
Resistance thermometer (Pt100)
Thermocouple (J,K,T,E,B,R,S,N,C)
Voltage/Current transmitter (mV/V/mA)

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

   
 
The IST-D DIN rail transmitter can be configuration using a PC with software and interface cable or hand carry adapter 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 supplier. During configuration the transmitter can work alone without connecting to a power source.
