Hello PLCTalk Friends,
I am interested in connecting one 2-wire loop powered 4-20mA transmitter to two analog input cards. In my program, I will compare the two channels on the different analog input cards to see if one of the cards is receiving a bad signal.
Will using two 1756-IF16 allow me to use all 16 channels for 16 loop powered transmitters this purpose?
My thoughts,
Connect Transmitter + to 24V
Connect Transmitter - to the Card1 Channel IN-0
Connect the Card1 I-RTN-0 to Card2 Channel IN-0
Connect the Card2 I-RTN-0 to RTN
Connect the RTN to 0V
Thank you for your help,
Del
