Short description
The circuit serves for checking the occupancy of four independent
blocks. Detection is based on the current consumption monitoring
of the blocks.
The output is a galvanically isolated.
Wiring
The blocks connected to the module rail output connector are
supplied by the current flowing along the common wire (Figure 1:
lower, thick blue line).
LEDs or digital feedback modules can be connected to the detector
outputs (upper outputs on the figure).
