OPERATION
INTRODUCTION
This chapter describes how to configure and use the RLY-6 relay
interface module. System operators can use this manual once the
Eclipse System has been correctly installed and the relays have been
assigned with the Eclipse Configuration System.
DESCRIPTION
The RLY-6 provides six independent single-pole, double-throw (SPDT)
relays that are directly controlled by the CPU card in the matrix frame.
Like the GPI-6, this interface connects to the matrix through the
separate RJ-45 accessory data connector on the matrix frame.
The Eclipse system supports up to 10 RLY-6 interfaces, for a total of 60
outputs. You can use a mix of GPI-6 and RLY-6 interfaces to support
up to a total of 60 outputs and/or inputs. For example, five RLY-6 and
five GPI-6 modules would provide 30 relays and 30 inputs for a total of
60 inputs/outputs.
All of the RLY-6 and GPI-6 interfaces in the system are daisy-chained
from the GPI/RLY connection on the matrix. The matrix system will
automatically identify both the type and "address" of every relay output
or logic input.
The front panel of the RLY-6 has six green LEDs to indicate the
operation of each of the relays in the module. A seventh yellow LED
indicates that the module is communicating with the CPU card in the
frame. There is also a TEST pushbutton switch for each relay to allow
local activation of a relay for test of hardware connected to the relay
contacts.
The RLY-6 interface module provides the following functions:
• Six independent sets of relay contacts which are activated from the
matrix.
• DC isolation between relay device(s) and the central matrix.
• An LED indicator for each relay that lights when the relay is active.
Each RLY-6 interface relay contact is a single-throw double-pole pair
for use by the user. They are rated at 1 ampere at 24 volts DC
(resistive load). The RLY-6 is not designed for switching mains AC line
voltage. To switch an external device that runs on the mains AC line
voltage, use an external relay that is activated by the RLY-6.
The RLY-6 relay interface
module provides six
independent, single-pole,
double-throw (SPDT) relays
that are directly controlled by
the matrix.
General purpose outputs are
also called “relays.”
