E-BUS 12-Relay Expansion Module
The E-BUS 12-Relay Expansion Module ( OE358-23E-12R-A)
provides for 12 Dry Contact Confi gurable Relay Outputs. See Figure
29 below for complete wiring details.
The E-BUS 12-Relay Expansion Module can be used in conjunction
with the VCC-X EM1 Expansion Module (OE336-23-VCCXEM1).
The expansion modules can be used individually or together to
provide the required inputs and outputs for your specifi c applications.

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 Modules must be wired in such a way that the expansion modules 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.
NOTE:
All Relay Outputs Are
Normally Open And Rated
For 24 VAC Power Only.
