SA Expansion Module
Two different Expansion Modules are available for use with the SA E-
BUS Controller to provide additional inputs and outputs beyond those
found on the SA E-BUS Controller.
The SA Expansion Module ( OE333-23-SA E-BUS 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.
