Using DIO Function (DIO with optional MezIO-Card only)
Wiring for DIO
The digital input function of System series is implemented using a photo-coupler with an internally
series-connected 1kΩ resistor. You need to provide a voltage to specify the logic high/low state.
The input voltage for logic high is 5~24V, and the input voltage for logic low is 0~1.5V.
The digital output function of System series is implemented using Power Analog
Device iCoupler® component. The DO channels are configured as NO (normally-open) configuration.
When you turn on system, all DO channels have a deterministic state of logic 0 (circuit discon-
nected from GND return). When logic 1 is specified, MOSFET is activated and GND return path is
established. The digital output function on System series supports sinking current connection.
The following diagrams are the suggested wiring for DO:
