E-BUS Modules and/or Sensors to VCB-X Controller Wiring
Figure 4: Multiple E-BUS Sensors Wiring to VCB-X Controller Using the E-BUS Adapter
Connecting Multiple E-BUS Modules
and/or Sensors to the VCB-X
Controller
If using multiple E-BUS Sensors or Modules, the E-BUS Adapter
Board can be used when there are not enough available E-BUS ports
on the Unit Controller.
Up to (3) E-BUS Modules or Sensors can be connected to the E-BUS
Adapter Board(s) MODBUS E-BUS ports. The VCB-X Control-
ler connects to the fourth MODBUS E-BUS port on the E-BUS
Adapter Board.
See Figure 4 for wiring details when connecting multiple E-BUS
modules and/or sensors to the VCB-X Controller.
