Wiring diagrams (optional modules)
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. VDC: power supply voltage output. Vo+: positive output contact
(open collector transistor). GND: ground output contact (open collector transistor).
