Power Supply 1CT and 1VT/PT connection
Open collector outputs: The load resistance (Rc) must be calculated 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 (external). Vo+: positive output contact (open collector transistor). GND: ground output contact (open collector transistor).
