12 Relay E-BUS Expansion Module
The ASM01873 12 Relay E-BUS Expansion Module provides
for 12 Dry Contact Congurable Relay Outputs. See Figure 30,
this page for complete wiring details.
The 12 Relay E-BUS Expansion Module can be used in
conjunction with the VCC-X EM1 Expansion Module. The
expansion modules can be used individually or together to
provide the required inputs and outputs for your specific
applications.

WARNING: Observe Polarity! All boards must be
wired with GND-to-GND and 24 VAC-
to-24 VAC. 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.
