4.5.6 Connecting to a GPI/RLY Interface
The RJ-45 connector labeled GPI/RLY Interface connects the Eclipse HX-PiCo matrix to a
GPI-6 or RLY-6 interface card. The GPI-6 provides six general-purpose opto-isolated logic
inputs. The RLY-6 module provides six single-pole, double-throw relay outputs.
Both card types mount in either an IMF-3 interface frame or an IMF-102 interface frame. Up to
ten GPI-6 or RLY-6 modules can be operated at one time from the matrix by daisy-chaining the
cards together. Each card has an IN and an OUT connector for this purpose.
The RLY-6 and GPI-6 interface modules connect to the GPI/RLY interface connector using
shielded CAT-5 cable.
Important note:
If this port is used a ferrite core must be added to the socket end of the cable. A suitable ferrite
core is Würth Electronik part: 74271132. A shielded cable should be used.
Tip: For more detailed information about connecting matrices to interfaces, see the
Eclipse HX Matrix Installation Guide.
Connecting to a RLY-6 Interface module
The RLY-6 relay interface module connects up to six programmable relays to the matrix so that
each relay is directly controlled from the matrix. Multiple RLY-6 interfaces can be daisy chained
to provide connection of up to 60 relays to the matrix.
RLY-6 interface module in an IMF-3 interface frame
To connect a RLY-6 interface that has been housed in an IMF-3 interface module frame to the
matrix:
1. Connect one end of an RJ-45 cable (eight wires with no reversal) to the GPI/RLY
INTERFACE connector on the back of the matrix.
2. Connect the other end of the RJ-45 cable into the top RJ-45 (CH. A MATRIX) connector
for the RLY-6.
To connect an additional RLY-6 interface module:
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 short RJ-45 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 interfaces, the inputs in the first interface are numbered 1 to 6 for RLY 1; in the
second interface 1 to 6 for RLY 2, etc. RLY interface 0 is the internal Matrix RLY interface.
