Description

MR50, Limit Value Switch for Standard Signals

The limit switch MR50 is used to monitor measured values.
The display range and units for the measured value can be shown on the display.
An integrated transmitter supply enables the direct connection of 2-wire sensors.
The device offers simple programming, has max. 4 alarm contacts (relay changeover) and optionally via a parameterizable, galvanically isolated analog output 0/4...20mA; 0/2...10V.
 
An Ex version of this limit switch is also available on request.
