General
The IRC5 controller may be fitted with I/O, Gateway or Encoder units. These are configured
in an identical way.
The IRC5 Single Cabinet Controller is prepared for up to two I/O units, Gateways or Encoder
interfaces units, and the Dual Cabinet Controller (Control Module) is prepared for up to four
I/O units, Gateways or Encoder interface units. This means that the harness inside the IRC5
controller is equipped with necessary connectors.
For the Single Cabinet Controller the I/O, Gateway or Encoder units are placed on the inside
of the door as shown in the illustration below. For the Dual Cabinet Controller the units are
mounted in the Control Module.
