input
terminal
1. Connect to 24V by default, J14 jumper on
main control board to 24V or COM
connection.
2. When external power is used to drive
DI1~DI5, HDI1, OPEN needs to connect to the
external power supply and disconnect
J14(disconnecting with +24V/COM).

1. Optical coupling isolation, compatible with
dual polarity input, internal resistance 3.3kΩ;
2. Multi-function digital input, through
F5-01-F5-05 to set function.
3. The inverter d24v power supply
built-in, COM is common terminal.
4. When using external power, JP14 should be
suspended, ex24V connect to OPEN
terminal, COM is common terminal(external
voltage supply range +24V±10%).

terminal
1. When used as general digit input, it is the
same function as DI1~DI5;
2. Can be combine with OPEN terminal as
bipolar high speed pulse input terminals, max
input frequency is 100kHz
。
3. When use external power, input voltage
range +24V±10%;
4. The internal impedance 1.65 kΩ
