and GPI-6 modules can be mixed together up to the total limit of 60
items. Five RLY-6 and five GPI-6 modules would provide 30 relays and
30 inputs for a total of 60 inputs and outputs.
Note: For Eclipse systems if both GPI-6 and RLY-6 interfaces are
used the GPI-6 interfaces must be placed first in the daisy
chain.
This restriction does not apply to Matrix Plus 3 systems where
interfaces can be mixed in this 'daisy-chained' scheme.
The RLY-6 interface has its own manual in the Eclipse manual set (part
810310Z). This discussion gives an overview of the wiring of this
interface.
IMF-3 Interface Module Frame Wiring
To Matrix Frame
To connect the RLY-6 to the matrix frame, plug one end of an RJ-45
cable (eight wires with no reversal) into the GPI/RLY INTERFACE
connector on the back of the matrix. Plug the other end into the top
RJ-45 (CH. A MATRIX) connector for the RLY-6.
To connect an additional RLY-6 interface, plug one end of a short
RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for the first RLY-6.
Then, plug the other end into the top RJ-45 (CH. A MATRIX) connector
for the additional RLY-6. Additional RLY-6 Interfaces are added in the
same way, using daisy-chain wiring. If there are multiple RLY-6
modules, the relays in the first will be numbered 1 to 6, second will be
7 to 12, etc. GPI-6 modules can be mixed in this daisy-chained
scheme. The maximum combined length of all the RJ-45 cables should
not exceed 20 ft. (6 m). Refer to Figure 4-19.
Note: For Eclipse systems if both GPI-6 and RLY-6 interfaces are
used the GPI-6 interfaces must be placed first in the daisy
chain.
