External Relay & Digital I/O Connections
The relay and digital I/O expansion modules PDA1004 & PDA1044 are
connected to the meter using the CAT5 cable provided with each mod-
ule. 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 op-
tional expansion module.
