F650-G-N-A-B-F-2-G-1-HI-C-E relay

The 5704 Series Control System is a microprocessor based system which displays the reading and status of connected gas detectors. The system provides complex alarm handling facilities with a full maintenance capability. A rack system is fitted with a number of Four Channel Control Cards each with an associated Quad Relay Interface Card which provides the necessary sensor input and optional relay output connections. A Relay Interface Assembly may be used to expand the number of relay outputs available for each of the Four Channel Control Cards. Simple alarm handling and operation is provided by each channel control card. Complex alarm handling is achieved by communication between a specified number of control cards via the backplane of the rack. An Engineering Card is fitted to each rack and provides control of the rack backplane communications, control card interrogation and facilitates maintenance. In small systems power supplies, auxiliary power supplies and battery back up systems can be connected to the rack via a DC Input Card. In heavily populated installations of more than eight Four Channel Catalytic Control Cards, power supplies are connected to each individual Four Channel Catalytic Control Card via its interface card.

FOUR CHANNEL CONTROL CARDS

RACKS All four versions have two separate chambers. One is sealed against electromagnetic interference and contains the control cards while the other chamber contains the relay interface cards. A backplane between the two chambers provides a path for signal routeing between individual control cards and the Engineering Card.

The 5704 Four Channel Control Card provides control, display and alarm facilities for up to four connected gas detectors. The front panel backlit display indicates the gas reading, channel status and channel number while LEDs are used for alarms. A push-button is provided for resetting the alarms and selecting the card for use with the Engineering Card. The operation of the control card is microprocessor controlled and is fully definable for a wide range of connected gas detectors and application requirements. The software configuration setup is stored in an EEPROM.

Optional Analogue Output Modules which provide a remote output of the channel card readings can be plugged into the Four Channel Control Card. One module is required per channel and different module types are available to permit either current source or current sink as required.

Control Functions

 The Four Channel Control Card carries out the control functions for up to four loops of gas detection as follows: a. Provides the necessary voltages and currents to drive the connected sensors. b. Processes the incoming sensor signals. c. Displays the signal levels, one at a time, on the front panel liquid crystal display. d. Compares each channel signal level with pre-defined alarm limits. e. When the pre-defined alarm limits are exceeded, raises the alarms by lighting up front panel LEDs and operating connected relays. f. Informs other cards with the alarm status information. g. Self validates the operation of its circuit components, software operation and the condition of the sensor. 4.3 Analogue Output Module Optional Analogue Output Modules may be factory fitted to the Four Channel Control Card and are used on each channel of gas detection to provide a 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, data logger, PLC, etc. Two versions are available: a. Analogue Output Module, Current Sink Part Number 04200-A-0145 b. Analogue Output Module, Current Source Part Number 04200-A-0146
