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 .

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.

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).

Note: If both GPI-6 and RLY-6 interfaces are used the GPI-6 interfaces must be placed first in the daisy chain

Wiring external devices to an RLY-6 interface module

To connect external devices to an RLY-6 interface module, use the two DB-9M connectors on the rear cable assembly panel for the interface module.

If a DB-9F is plugged into the connector labeled CH. A I/O, relays 1 to 3 are available on that connector. The connector labeled has the contacts for relays 4 to 6.

Note: In the following image the labels on the pins apply to either connector. For example, #1/4 COM refers to the wiper of relay 1 if it is connected to CH. A and the wiper of relay 4 if it is connected to CH. B.

Wiring the RLY-6 to an IMF-102 interface frame

The wiring of an RLY-6 interface that is placed in an IMF-102 interface frame is the same as the wiring for a RLY-6 interface placed in an IMF-3 interface frame (see the Wiring the RLY-6 to an IMF-3 interface frame image.

The only difference is that an IMF-102 interface frame houses only two interfaces, which are mounted horizontally rather than vertically in the frame.

Note: IMF-3 rear panel and IMF-102 rear panel images illustrate the differences between these interface frames.

For more information, see your IMF-102 and IMF-3 documentation.

To associate a relay to a label, use the EHX configuration software (see your EHX documentation and EHX Help).
