dc (10…60V) Output Module 7

Publication 1771-IN054C-EN-P - November 2006

Connect Wiring

Connect your I/O devices to the field wiring arm, 1771-WH, shipped with the module.

You can use an ac (24V) output module, 1771-OND series C, to directly drive terminals on an
ac/dc (24V) input module, 1771-IND series C, as shown in the connection diagram on
page 8.

WARNING

When you connect or disconnect the wiring arm with field-side power applied, an
electrical arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.

WARNING

Permanent damage to the module may occur in applications where frequent overload or
short circuit conditions are possible. To prevent module damage where these conditions
exist, use the optional 1771-WHF or 1771-WHFB fused field-wiring arm instead of the
1771-WH field-wiring arm shipped with the module. Note that the optional 1771-WHF or
1771-WHFB fused field-wiring arms are not certified for use in Class I, Division 2, Groups
A, B, C, and D environments.

ATTENTION

Remove power from the 1771 I/O chassis backplane before you install this module.
Failure to remove power from the backplane could cause:

• module damage or degradation of performance.
• injury or equipment damage due to possible unexpected operation.
