Pt100 to telefast.

Dear,

I have to connect pt100(2wire) in telefast module ABE7CPA412. I have check the wiring manual and it is confusing. Can you pls share the rough sketch on how to connect pt100 with telefast? 

Thanks in advance.

Is your ABE7CPA412 connected to a BMXART0414 or BMXART0414 with the appropriate BMXFCA152/302/502 cable?

For each pt100 probe you use you'll need to connect one wire to the coresponding MS+ and EX+ terminals and the other wire to the MS-and EX- terminals.

That would end up looking something like this:

MS0+ and EX0+ (102 and 100) A Wire
MS0- and EX0+ (103 and 101) B Wire

MS1+ and EX1+ (106 and 104) A Wire
MS1- and EX1+ (107 and 105) B Wire

MS2+ and EX2+ (202 and 200) A Wire
MS2- and EX2+ (203 and 201) B Wire

MS3+ and EX3+ (206 and 204) A Wire
MS3- and EX3+ (207 and 205) B Wire

If all you need to know is wiring you can stop reading now, else:

In the setup for the BMXART module select "Internal Telefast" for your cold juction compensation (which really only matters if you use thermocouples), select the appropriate rejection for your country's electrical grid frequency, chose "Pt100IEC (2/4 wires)" for the chanel range, and set the scale to C or F. The deafult scaing, and my preference is the tempurage range expressed as a 100x scaled integer.
