12-Relay Expansion Module
Three different Expansion Modules are available for use with the VCM-X
E-BUS Controller to provide additional inputs and outputs beyond those
found on the VCM-X E-BUS Controller. They are the VCM-X Expan-
sion Module (OE333-23-EM), the 4 Binary Input Expansion Module
( OE356-01-BI) which can be used in place of the VCM-X Expansion
Module if your system does not need any other inputs or outputs, and
the 12-Relay Expansion Module ( OE358-23-12R).
The 12-Relay Expansion Module provides for 12 Dry Contact Confi gu-
rable Relay Outputs. See Figure 31 below for complete wiring details.
The expansion modules can be used individually or together to provide
the required inputs and outputs for your specifi c applications.
When using the 12-Relay Expansion Module, you must correctly confi g-
ure a set of jumpers on the board depending on whether it will be used
by itself or in addition to the VCM-X Expansion Module.
The jumpers are located on the edge of the 12-Relay Expansion Module
on the same side of the module as the power connection. See Figure
31 below for details regarding setting the switch correctly for your
application.

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.
