Connection to a PLC
Most digital PLC inputs are designed for connection to PNP signals. The MAG-VIEW™ has an NPN frequency signal with an integrated 2kΩ pull-up resistor. Its signal current of ~12 mA is recognised as a signal by the current PLC. Thus, operating a MAG-VIEW™ with a PLC should not present any problems. The frequency output of the MAG-VIEW™ should be attached to a digital input of the PLC.
