Fig. 4-7: Sensor connection
2-conductor sensors, e. g. switches, are connected to the grey and red terminal
blocks.
3-conductor sensors receive their 24 VDC supply voltage through the connec-
tion to the red and the blue terminal blocks. The output signal of the
3-conductor sensor is connected to the grey terminal block.
