12-Relay 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) is provided with 8 Binary
Inputs, 4 Analog Inputs, 4 Relay Outputs, and 5 Analog Outputs. See
Figures 16 and 17 on page 20 and 21 for complete wiring details.
The 12-Relay Expansion Module ( OE358-23-12R) provides for 12 Dry
Contact Confi gurable Relay Outputs. See Figure 25 below for complete
wiring details.
