External Relay & Digital I/O Connections
The relay and the digital I/O expansion modules PMA-11 & PMA-12 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 PMA-12
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.
