· The input voltage range of the GPI inputs is +5 to +30 VDC (~5 mA current draw, internal optocouplers).
· The polarity of the inputs is important. The higher potential must be connected to “P” of each channel.
· The inputs are galvanically isolated.
· The "GPIO +5V" output voltage drops when increasing the: 5V @ 0mA / 3.3V @ 50mA.
· The switching threshold is between 0.8 VDC and 2.0 VDC.
