Dual Digital Module Wiring
The Dual Digital Module directly connects to the VCM-X Modular E-
BUS Controller using a modular HSSC cable. The Dual Digital Module
requires a 24 VAC power connection with an appropriate VA rating. See
Figure 5 below for wiring.
Any E-BUS Module can be connected to the E-BUS Controller’s E-BUS
port or can be daisy-chained together using HSSC cables.
NOTE: Contact Factory for the correct HSSC cable length for
your application. Cables are available in ¼, ½, 1, 2, 3,
4, and 5 Meter lengths and 100 and 150 Foot lengths.

WARNING!!
Observe Polarity! All boards must be wired with
GND-to-GND and 24 VAC-to-24 VAC. Failure to
observe polarity could result in damage to the
boards.
