SA Expansion Module
Two different Expansion Modules are available for use with the SA
Controller to provide additional inputs and outputs beyond those found
on the SA Controller.
The SA Expansion Module ( OE333-23-SA Controller) provides 8 Binary
Inputs, 4 Analog Inputs, 5 Analog Outputs, and 4 Confi gurable Relay
Outputs. See Figures 16 and 17 for complete wiring details.

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 Module must be wired in such a way that the
expansion module 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.

The 12-Relay Expansion Module ( OE358-23-12R) provides for 12
Dry Contact Confi gurable Relay Outputs. See Figure 25 for complete
wiring details.
The expansion modules can be used individually or together to provide
the required inputs and outputs for your specifi c applications.
