External Relays & Digital I/O Connections
The relay and the digital I/O expansion modules PDA1004 & PDA1044
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
PDA1044 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.
