Honeywell 05701-A-0440 Power supply 50W module

PRINCIPAL FEATURES

The 5704F Series Control System is part of the System 57 family and is designed to monitor field mounted industrial fire detectors. 

High Integrity Relay Card (Part Number 05701-A-0330)

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.

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.

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.

The Engineering Card is always fitted into the right-hand slot of the rack and provides:

a. Routeing of the 24V dc input from the DC Input Card to the backplane of the rack.

b. A backplane serial communications controller and monitor.

c. A time and date reference.

d. An RS232 external engineering interface.

e. Depending upon the security level, the operation of the following rack facilities:

Catalytic sensor head current monitoring and adjustment.

Alarm set point checking, adjustment and testing.

Sensor signal zero adjustment.

Sensor signal span adjustment and setting of sensor life monitoring values.

Sensor line monitoring.

Enabling of control card alarm inhibit.

Checking and adjustment of the system clock.

Single Channel Control Card Physical Layout

The physical layout of the Single Channel Control Card is shown below.

The Sensor Drive Modules plug into the 14-way connectors J1 and J2

while the Analogue Output Module, when fitted, plugs into J3 and J4.

Link LK1, available on MkII cards only, is used when individually powering

control cards See Chapter 4, Section 16.2.

Architecture

The system consists of a single 1'' (2.54 cm) wide board mounted in a ruggedized rack designed for European style cabinets.

Two rack widths are available:

a. 19-inch with 17 card slots for up to 16 channel control cards and one engineering card.

b. Half 19 inches with 9 card slots for up to 8 channel control cards and 1 engineering card.

Each subrack contains one engineering card and one DC input card to form the rack system.

The system is designed to accommodate different customer wiring configurations, and for this reason, 

the control functions are separated from the relays and field wiring connections.

Therefore, single channel gas detection consists of :

a. Sensor Driver Module

For compatibility with a wide range of input and sensor types, the circuitry required to control the sensors is mounted on separate plug-in sensor driver modules.

These modules plug directly into the channel control card and are factory installed. 

Two different modules are available, one for catalytic inputs and the other for 4 - 20mA inputs.

b. Single Channel Control Cards

Each single-channel control card is self-contained and contains all the necessary electronic circuitry to provide sensor actuation, 

alarm detection, and gas level indication for that gas detection channel.

c. Field Interface or Relay Card

Field interface/relay cards provide interface connections between the control card and the respective field-connected gas sensors. 

In addition, relay cards provide alarm outputs for field connections.
