Transducer Inputs/Outputs - GE UR Series Instruction Manual

3.2 WIRING
Transducer input/output modules can receive input signals from external dcmA output transducers (dcmA In) or resistance
temperature detectors (RTD). Hardware and software is provided to receive signals from these external transducers and
convert these signals into a digital format for use as required.
Every transducer input/output module has a total of 24 terminal connections. These connections are arranged as three ter-
minals per row with a total of eight rows. A given row may be used for either inputs or outputs, with terminals in column "a"
having positive polarity and terminals in column "c" having negative polarity. Since an entire row is used for a single input/
output channel, the name of the channel is assigned using the module slot position and row number.
Each module also requires that a connection from an external ground bus be made to Terminal 8b. The figure below illus-
trates the transducer module types (5C, 5E, and 5F) and channel arrangements that may be ordered for the relay.
Wherever a tilde "~" symbol appears, substitute with the Slot Position of the module.
