05701-A-0361

a single loop of gas detection as follows:

Processes the incoming sensor drive module signal.

Displays the signal level on the front panel liquid crystal display.

Compares    the    signal    level    with    pre-defined    alarm    limits.

When    the    pre-defined    alarm    limits    are    exceeded,    raises    the    alarms

by lighting up front panel LEDs and operating optional connected

relays.

Informs other cards with the alarm status information.

Self validates the operation of its circuit components, software

operation and the condition of the sensor.

Sensor Drive Modules

Two sensor drive modules are provided:

Sensor Drive Module, 4 – 20mA, Part Number 05701-A-0283

Sensor Drive Module Catalytic,

Part Number 05701-A-0284

The Sensor Drive Module conditions the incoming catalytic or 4 – 20mA

sensor signal and provides the necessary sensor power supply. It

contains all the circuitry necessary to generate the voltages and currents

required to drive the sensor, the circuitry to acquire the sensor signal

and to scale the sensor signal to a standard output. The sensor drive

modules    are    factory    fitted    and    plug    directly    onto    the    channel    control

card.

Analogue Output Module

An optional Analogue Output Module, (Part Number 05701-A-0285),

may    be    factory    fitted    to    the    Single    Channel    Control    Card    and    is    used

on a channel of gas detection to provide an isolated current loop output

which follows the sensor signal level. This may be set electronically to

produce a 0 – 20mA output or a 4 – 20mA output and can be used to

operate a chart recorder, etc.

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

5.1

FIELD INTERFACE AND RELAY CARDS

General

The Field Interface Card and the four types of relay card provide the

interface    between    a    Single    Channel    Control    Card    and    the    field    wiring.

5.2

Field Interface Card (Part Number 05701-A-0326)

5.2.1 General

For use in systems with master relays. Used on all channels except

the master. Provides connections between the sensor and the control

card    only.    No    relays    fitted.

Double SPCO Relay Card (Part Number 05701-A-0327)

5.3.1 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 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.
