The electronic limit value relay GMA… with display is used to monitor alternating current or direct current as well as alternating voltage or direct voltage. The alternating current values are measured as an effective value with any waveform. The measured value or limit value are displayed on a 2-digit LED display

The limit value can be set using buttons on the front of the unit in increments of 1%. Hysteresis, switch-on and switch-off delay and closed-circuit or open-circuit current principle can also be set using the buttons

If the limit values are exceeded, this is indicated via light- emitting diodes. The limit value relay are installed in a housing of 22,5 mm of breadth and can be attached to a top hat rail in snapping them on.
