External Relay & Digital I/O Connections
The digital I/O expansion module 60101044 are connected to the controller using a CAT5 cable provided
with each module. The two RJ45 connectors on the expansion modules are identical and
interchangeable; they are used to connect additional modules to the system.
Note: The jumper located between the RJ45 connectors of the 60101044 must be removed on the
second digital I/O module in order for the system to recognize it as module #2.
Warning!
Do not connect or disconnect the expansion
modules with the power on!
More detailed instructions are provided with each
optional expansion module.

Interlock Relay Feature
As the name implies, the interlock relay feature reassigns one, or more, alarm/control relays for use as
interlock relay(s). Interlock contact(s) are wired to digital input(s) and trigger the interlock relay. This
feature is enabled by configuring the relay, and relative digital input(s) (see page 34). In one example, dry
interlock contacts are connected in series to one digital input which will be used to force on (energize) the
assigned interlock power relay when all interlock contacts are closed (safe). The interlock relay front
panel LED flashes when locked out. The interlock relay would be wired in-series with the load (N/O
contact). See below.
