6.11.5 Wiring scheme for the RLY-6 interface module
The RLY-6 interface module provides six fully programmable SPDT (single pole, double
throw) relay outputs, to support dedicated switching functions external to the matrix frame .
RLY-6 interfaces can be:
• Daisy chained to provide connection of up to 60 relays to the matrix.
• Mixed with GPI-6 modules 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:
If both GPI-6 and RLY-6 interface modules are used the GPI-6 interface module must be
placed first in the daisy chain.
Tip: For more information about wiring the RLY-6, see the RLY-6 manual.
Wiring the RLY-6 to an IMF-3 interface frame
To connect the RLY-6 to the IMF-3 frame:
1. Connect one end of an RJ-45 cable (eight wires with no reversal) into the GPI/RLY
INTERFACE connector on the back of the matrix.
2. Connect the other end into the top RJ-45 (CH. A MATRIX) connector for the RLY-6.
To connect an additional RLY-6 interface to the IMF-3 frame:
1. Connect one end of a short RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for the
first RLY-6.
2. Connect the other end of the cable 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 module will be numbered 1 to 6, the relays in
the second module will be numbered 7 to 12, and so on. 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 feet (6 m).
