The GDA 2400 control unit can take up to 8 x 4-20 mA i/ps. The controller selects the highest reading from the sensors and displays the highest reading of gas from the sensors. This controller is used when ALL the gas sensors are the same type. It is particularly useful in Periphery monitoring and CAR PARK Ventilation control. There are 3 programmable relay alarm levels. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V o/p’s. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 240 VAC.
