External Relay & Digital I/O Connections
The relay and the digital I/O expansion modules 7ML19306AC &
7ML19306AD are connected to the meter 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
7ML19306AD 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.
