SA Expansion Module Binary Inputs
The SA Expansion Module provides 8 Binary Inputs. See Figure 19
below for detailed wiring.
The transformer used for powering the SA Expansion Module must also
be used to power the binary inputs.
Figure 19: OE333-23-SA – SA Expansion Module 8 Binary Inputs Wiring
Warning: Do not apply any voltage greater than 24 VAC to the
binary inputs. Higher voltages will damage the expansion module
and possibly other components on the system.

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.
