[169] Main circuit for signal inputs (PNP).
1) With 3.8 mA input current
2) With 5.7 mA input current
3) 24 V input

5 V microcontroller input
Circuit diagrams for signal outputs
All signal outputs are designed as PNP and are galvanically separated from the 5 V control system
(optocoupler).
The maximum output power drawable from the 24 V supply is 24 W (1 A). This is the sum of all sen-
sor supplies and of all switch outputs which are active at the same time.
