CXCI/CXCI+ I/O Terminal Block
A CXCI/CXCI+ I/O terminal block kit is installed in the UDC front door for front access to controller signals and
interfaces to the CXCI/CXCI+
controller on the converter shelf via a 25-pin D-sub wire harness.
The internal signals from the distribution center are wired to the CXCI/CXCI+ I/O board direct from the internal
alarm board. The remaining relay outputs, digital inputs, and analog inputs are available on the board via terminal
blocks for customer connection of external signals. Refer to the customer connections (“–08”) drawing at the rear
of this manual for details on terminal block assignments.

4R/8D ADIO (Option)
The 4R/8D ADIO Cordex peripheral may also be optionally installed on the front door of the DCP03 expanding the
I/O capability of an existing Cordex controller by adding an additional 4 relays outputs and 8 digital inputs.
The 4R/8D ADIO installs on the right side on the front door. The ADIO is connected to the Cordex system via CAN
communications using RJ-12 offset communications cables.
All I/O connections are made via screw terminal blocks. Refer to the customer connections (“–08”) drawing at the
rear of this manual for details on terminal block assignments.
NOTE:
The 4R/8D ADIO board does not come with the CXPS 24-48-i system and is purchased separately. Consult
factory for options.
