Rockwell Automation 1771-IBN DC (10-30V) INPUT Module Installation Instructions - Manual (Page 11)

DC (10...30V) Input Module 11
Publication 1771-IN028D-EN-P - October 2008
I/O Module Groups
Each module condenses two full-module groups (32 inputs) into each I/O chassis slot. For
example:
• module group 1 = inputs 00…17.
• module group 2 = inputs 00…17 (module group 2 represents the second set of
inputs).
In the graphic on the following page, note the following:
• Terminals 1…20 represent module group 1, with terminals 9, 10, 19, and
20 DC common.
• Terminals 21…40 represent module group 2, with terminals 29, 30, 39, and
40 DC common.
• Terminals on the left are even numbered 2…40 and terminals on the right
are odd numbered 1…39.
• If multiple power sources are used, do not exceed the specified isolation voltage.
• The arrow in the figure shows that actual wiring runs in this direction.
ATTENTION
Observe proper polarity with DC power connections. Reverse polarity or application of AC
voltage could damage the module.
