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.
