INTERFACE ASSEMBly
5.1

General

The Quad Relay Interface Card provides the interface between a Four
Channel Control Card and the field wiring.
An Expansion Relay Card can also be factory fitted to the Quad Relay
Interface Card and the resultant assembly is then known as the Relay
Interface Assembly. This assembly is used to expand the standard four
relays available for alarms on the Quad Relay Interface to 16 relays.
5.2 Quad Relay Interface Card (Part Number 05704-A-0121)
5.2.1 General
Provides connections between the four sensors and the control card.
In addition, four single pole relays provide voltage free contact outputs
that can be configured for the A1 alarm level, A2 alarm level, A3 alarm
level, fault or inhibit conditions and as individual alarms or master
alarms. Connections for power, remote inputs and analogue outputs
are also provided.
The front and rear access connections are shown in Sections 5.2.2 and
5.2.3 respectively while the physical layout is shown below:
