Your advantages in detail

Simply choose the desired monitoring function via the rotary switches on the front of the housing.

Threshold values and response delays can be finely controlled via potentiometers, enabling even small deviations to be detected quickly.

EMD monitoring relays can be used worldwide in your applications – without an additional power supply unit. Two versions are available:

• Monitoring relay with integrated wide-range power supply unit for voltages from 24 V to 240 V.
• Monitoring relay with plug-in transformer for adjusting the supply voltage, graded in various voltage ranges from 24 V to 500 V.

EMD monitoring relays save valuable space in the control cabinet. With a design width of just 22.5 mm and two PDT contacts, they are the narrowest devices in their class.

Measuring and power circuits are electrically isolated from one another – providing added safety.

Everything at a glance – color status LEDs on the front of the housing indicate the following device states:

• Ready to operate
• Threshold value overrange or underrange
• Relay states

At the same time, a relay output is set for alarm indication at a controller.
