Wormald 2003A System Gas Control - 01-21-24
The 2003A Gas Control module is used to monitor for the presence of flammable vapours.
The module will accept three core connections from any catalytic gas sensor of the pellistor type in common usage. The seven segment LED display gives the concentration of gas detected, as a percentage of the lower explosive limit (% LEL), whilst over and under-range displays are identified by distinctive display indications.
The analogue output from the module are user selectable to mV or mA by means of a switch on the daughter circuit board which may be sealed in the required position.
The module provides indication and output signals for alarm, inhibit and fault conditions and with other modules in the range, is capable of utilising the SYSTEM TEST facility that the system offers.
The module has input voltage regulation, an on-board fuse and fuse failure and indication facilities.
