Maximum Control

The GMA 81A controllers will accept a signal from any one transmitter and the GMA 84A can control and monitor up to four GfG sensors of the same type. The three digit LED displays the transmitter readings; status LEDs verify operation and indicate alarm points and sensor faults. Additionally, if an alarm point or sensor fault occurs, the case mounted alarm horn and light will sound a warning and activate or deactivate the on board relays.

Flexible and Adaptable

Once programmed for a gas, the controller can be adapted to its application. Three alarm points which can be easily adjusted in the field and one fault alarm will trigger voltage free contacts to activate or deactivate external devices like fans, horns, auto dialers etc. The GMA 81A is equipped with a linear 4-20mA output for easy connection to recorders, meters, or PLCs. Menu driven zero point adjustment and calibration are easily performed with the keypad to make maintenance and calibration simple.
