External Relay & 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 iden-
tical 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.
