The 6.2 mm wide MINI MCR-SL-NAM-2RNO.... is a configurable 4-way isolation amplifier. It is suited for the operation of proximity sensors in acc. with EN 60947-5-6 and switches and also has two relay outputs. The second output can either be used to duplicate signals or for signaling faults for the sensor line.
The DIP switches are accessible on the housing side and allow the following parameters to be configured:
– Switchover from open circuit to closed circuit current behavior
– Activation of line fault detection of the sensor line as well as
– Selection of signal duplication/fault signaling
Power (19.2 V DC to 30 V DC) can be supplied through connection terminal blocks on the modules or in conjunction with the DIN rail connector.
