External Device I/O Terminals
External Device Input Terminals (In1, In2)
The external device input terminals consist of 2 terminals (In1 and In2), one of which is '+' (red) and another is
Connect any sensors and switches to terminals with electrically separate GND terminals and power supplies.
External Device Output Terminals (Out1, Out2)
The external device output terminals consist of 2 white terminals (Out1 and Out2). Both terminal combinations are peers. The Internal controller switches the two output terminals to disconnected or connected condition. The output terminals use optocouplers and are separate from the internal circuit in the VB150. Loads connected to the output terminals should be within the following ratings:
Rating across the output terminals
DC : Up to 50V
Continuous load current: 200 mA
