SA Controller Wiring

SA Controller

The Series A Controller (OE332-23-SA)—SA Controller—is designed

with 6 analog inputs, 2 analog outputs, and 5 relay outputs. Most com-

mon HVAC unit control applications can be conﬁ gured using only the

SA Controller; however, if needed, the SA Controller’s input and output

capabilities can be expanded with the SA Expansion Module ( OE333-

23-SA) or 12-Relay Expansion Module ( OE358-23-12R) by means of

a modular cable.

NOTE: Only one SA Controller is required whether the SA Unit

is a Single Cabinet or Dual Cabinet Unit. Additional wiring for

Dual Cabinet Units is shown and noted as such on the applicable

Single Cabinet Unit Diagrams.
