Rockwell Automation 1771-ICD DC(20-60V)Input Module Installation Instructions - Manual (Page 5)

5 DC (20-60V) Input Module Cat. No. 1771-ICD Series B
Publication 1771-5.29 – February 2000
Connect one terminal of your 2-wire input device to terminals 00
through 17. Connect the +dc line to the other terminal of your input
devices.
Connect terminal E to the dc common. Terminals A thru D are not
used. Use stranded 14 or 16 gauge wire to minimize the voltage drop
over long cable distances.
Connect 3-wire input devices, such as Allen-Bradley proximity
switches (Bulletin 871), to operate in a current source mode.
(Actual wiring runs in this direction.)

Important: You can directly drive terminals on a DC (20-60V)
Input Module (cat. no. 1771-ICD) from terminals on the
following modules:
•
DC (10-60V) Output module (cat. no. 1771-OBD)
•
DC (48V) Output module (cat. no. 1771-OC)
•
DC (12-24V) Output module (cat. no. 1771-OB)
Important: Use the same dc power source to power both
modules to ensure that ground is at the same
potential.
