The expansion modules can be used individually or together
to provide the required inputs and outputs for your specic
applications.
NOTE: A total of 17 relays are available by adding the
Relay Expansion Modules. All Expansion Module
relay outputs are user-congurable.
WARNING: Observe Polarity! All boards must be
wired with GND-to-GND and 24 VAC-
to-24 VAC. Failure to observe polarity
will result in damage to one or more of the
boards. Expansion modules must be wired
in such a way that the expansion modules
and the controller are always powered
together. Loss of power to the expansion
module will cause the controller to become
inoperative until power is restored to the
expansion module.
