·
The input voltage range of the GPI inputs is +5 to +48 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 by increasing the load: 5V @ 0mA / 3.3V @ 50mA.
