Rockwell Automation 1771-IBD INSTL INSTR DC (10-30V) INPUT - Manual (Page 5)

DC (10-30V) Input Module 5
Publication 1771-5.53 – April 1999
Make wiring connections to the field wiring arm (cat. no. 1771-WH)
shipped with the module.
1. Connect one terminal of your two or three-wire input device to
terminals 00 through 17.
2. Connect the +dc line to the other terminal of your input devices.
Connect three-wire input devices, such as Allen-Bradley
proximity switches (Bulletin 871), to operate in a current source
mode.
3. 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.
!
ATTENTION: Observe proper polarity with dc power
connections. Reverse polarity, or application of ac
voltage could damage the module.
