Publication

1794-IN108D-EN-P - January 2014

Ground the Module

All I/O wiring must use shielded wire. Shields must be terminated external to
the module, such as bus bars and shield-terminating feed-throughs.

Inputs

Each input can be operated from an analog field device signal.
The channels in these modules are electrically connected to each other and
have a common plus-line.

IMPORTANT

When interconnecting several lines, you must consider the total accumulated
power.
