A Programmable & user-friendly converter, was born.
ISC Dual Channel Isolated Signal Subtraction Conditioner/Converter
 

Feature:
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 (mV/V/mA)
The unique Math function:

   PV1 ¡G Input 1 ; PV2 ¡G Input 2
   A ¡A B ¡A C ¡G Constant Factors are set by user
   When Subtraction ¡]¡Ð¡^ function is selected, calculation    formula is as followings.

   PV1¡GInput 1
   PV2¡GInput 2
   A¡AB: Constant Factor A or ,B>0 and C=1, ¡Ô : disable
Output device:
   1.ISC-S : Single Analog Output: 4 ~20 mA¡B0~10VDC ¡K
   2.ISC-D: Dual Analog Outputs: 4 ~20 mA¡B0~10VDC ¡K
   3.ISC-C : One Analog Output(OUT1) 4 ~20 mA¡B    0~10VDC ¡K with RS485 Com port : MODBUS-RTU    (OUT2) ¡Kand One RS485:MODBUS-RTU (OUT2)
High accuracy in total ambient temperature range.
Fault signal on sensor break presettable.

   
 
The Din Rail converter 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 supplier. During configuration the converter can work alone without connecting to a power source.
