GVC736CE101 3BHE039203R0101 Thyristor module

Field Interface or Relay Card The Field Interface/Relay Cards provide the interface connections between the Control Cards and their respective field connected gas sensor. In addition, Relay Cards provide alarm outputs to the field connections.In a system where the field wiring is required to be connected to the rear of the system, the rack is centrally divided into front and rear sections by a printed circuit board backplane which provides common power and signal routeing between individual Channel Control Cards. Channel Control Cards are fitted at the front of the rack while Interface/ Relay cards are fitted directly behind the Channel Control Cards at the rear of the rack. The Channel Control Cards and their respective Interface/Relay Cards are interconnected by a plug and socket arrangement.

In a system where the field wiring

 is required to be connected to the front of a system, the Channel Control Cards and Interface/Relay Cards are mounted one above the other in a 6U rack. The backplane printed circuit board still provides the common power and signal routeing between the individual Channel Control Cards while short cables at the rear of the cards connect each Channel Control Card to their respective Interface/Relay Card. Simple calibration and checking of the system is carried out using push buttons on the Engineering Card fitted to each rack. More complex configuration can be carried out using the RS232 link between the Engineering Card and an external IBM compatible personal computer running the engineering interface software.

Additional functions can be provided

 by the Engineering Card using optional modules that plug into the Engineering Card. See the following module operating instruction manuals: 05701M5006 Modbus Interface Module 05701M5007 Event Printing Module 05701M5008 Master Alarm Update Module The 5701 Control System is shown in Figure 1 with an overview at Figure 2 The 5701 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.
