WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-24VAC. 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.
Note:
All Relay Outputs Are Normally Open
And Rated For 24 VAC Power Only.
1 Amp Maximum Load.
The expansion modules can be used individually or together to provide
the required inputs and outputs for your specifi c applications.
When using the 12-Relay Expansion Module, you must correctly confi g-
ure a set of jumpers on the board depending on whether it will be used
by itself or in addition to the SA Expansion Module.
The jumpers are located on the edge of the 12-Relay Expansion Module
on the same side of the module as the power connection. See Figure
25 below for details regarding setting the switch correctly for your
application.
