Wiring diagrams (optional module)
Only open collector outputs: the grounds of the outputs are separated, and therefore it’s possible to carry out, for the same module,
two different connections. The load resistance (Rc) must be designed so that the closed contact current is lower than 100mA; the
VDC voltage must be lower than or equal to 30V.
