Provides connections between the sensor and the control card in
the same way as the Field Interface Card. In addition, single pole
relays provide voltage free contact outputs for the A1 alarm level,
A2 alarm level and fault condition.Triple SPCO Relay Card (Part Number 05701-A-0328)
5.4.1 General
Provides connections between the sensor and the control card in
the same way as the Field Interface Card. In addition, single pole
relays provide voltage free contact outputs for the A1 alarm level,
A2 alarm level, A3 alarm level, fault and inhibit conditions.
5.4.2 Rear Access Connections
Provides connections between the sensor and the control card in the
same way as the Field Interface Card. In addition, single pole relays
provide voltage free contact outputs for 2 x A1 alarm level, 2 x A2
alarm level, 2 x A3 alarm level, fault and inhibit conditions.
High Integrity Relay Card (Part Number 05701-A-0330)
5.6.1 General
Provides connections between the sensor and the control card in the
same way as the Field Interface Card. This card is used to provide
master alarm functions or a mixture of master and individual alarms. The
card is fitted with eight relays, seven of which are fully configurable while
the eighth is used for fault alarm. The relay states are monitored by the
control card to ensure correct operation of the relays. In the case of a
malfunction, the fault relay of the high integrity relay card de-energises.
The fault relay shall always be monitored in order to ensure correct
operation of the system.
Additional capabilities are available with this card including delayed
switch on or switch off of the alarm relays.
Note: The High Integrity Relay Card can only be used with MKII
Control Cards
ENGINEERING CARD
The Engineering Card (Part Number 05701-A-0361) is used on a
System 57 rack to provide a common interface that enables the user
to perform all the required functions to commission and operate each
fitted control card.
f. Self validation of the operation of its circuit components, software
operation and the backplane communications.
The front panel is fitted with a series of tactile
push-buttons for the operation of various functions,
LEDs to provide rack power and communications
status and a mini DIN socket for the connection of
a serial printer, computer or an engineering key.
The Engineering Key is used to unlock functions
that can alter the operation of a control card.
