The group of five terminals at the lower left of the module serves two separate functions.
The two terminals on the left of the group (P+ and P-) provide a 12Vdc source for digital
input signals (Figure 3-16). The three terminals on the right side of the group are the
COMMS cable connections:
•
C+ = RS 485 (+) Signal
•
C- = RS 485 (-) Signal
•
SHLD = Comms cable shield
The MP REM accepts up to four isolated, switched-contact, digital inputs. Refer to Table
3-18 for DIGITAL INPUT signal terminal identification. The digital inputs can use the P+
and P- terminals as a 12Vdc signal-source or, alternatively, an external 24Vac source can be
used. Figure 3-16 shows how the digital inputs can be wired in either of the two
configurations.
