Using DIO Function
Wiring for DIO
The digital input function of Nuvo-3100 series is implemented using a photo-coupler with a
internally series-connected 2.4k
Ω
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 Nuvo-3100 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 disconnected from GND return). When logic 1 is
specified, MOSFET is activated and GND return path is established. The digital output
function on Nuvo-3100 series supports sinking current connection. The following diagrams
are the suggested wiring for DO:
