Publication 1771-IN054C-EN-P - November 2006

Connection Diagram

You must supply dc at terminals A through D on the wiring arm. You need four dc

connections to accommodate the total required surge rating on the module without

overstressing any single connection on the field wiring arm. Jumper all dc connections

together to prevent module damage. Connect terminal E to dc common.

dc (10…60V) Output Module 9

Publication 1771-IN054C-EN-P - November 2006

Refer to Driving an Input with an Output Module on page for direct connection to a

1771-ICD input module.

ATTENTION Observe proper polarity, as indicated in the connection diagram on page 10 with dc

power connections. Reverse polarity, or application of ac voltage, could damage the

module.

IMPORTANT You can use a dc (10…60V) output module (771-OBD series C) to directly drive

terminals on the following modules:

•dc (5…30V) input module (1771-IQ)

•dc (10…30V) input module (1771-IBD, 1771-IBN)

•dc (20…60V) input module (1771-ICD)

•dc (12…24V) input module (1771-IB)

•dc (24V) input module (1771-IQ16)

•dc (48V) input module (1771-IC)

IMPORTANT Use the same dc supply to power both modules to make sure that ground is at the same

potential.
