DO1-COM
Digital output
1
1. Optical coupling isolation, dual polarity
open collector output;
2. Pull-up voltage range: 5V~24V (pull-up
resistance range: 0.48kΩ~10kΩ);
3. Output current range: 2mA~50mA.
HDO1-COM
Rapid pulse
input terminal
1. When used as general digital output, same
function as DO1;
2. Can be combined with the OPEN terminal
as bipolar high speed pulse output terminals,
max output frequency is 100kHz;
3. Pull-up voltage range: 5V-24V(pull-up
resistance range: 0.48kΩ~10kΩ).
4. Output current range: 2mA~50mA
Relay Output

Ground
PE
Shield cable
ground
terminal
1. Used to control cable shield grounding,
when the interference is big on site or control
cable is too long, the PE should be well
grounded to reduce EMC affect.
2. PE terminal is not allowed to connect with
power N line, otherwise will damaged the
inverter
