and the external sensor.
2. The maximum output current is 200mA.
OPEN
External power
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).
Communication

communication
terminals
Standard RS-485 communication terminal,
should use twisted pair cable
AI1-GND
Analog input
terminal 1
1. Input Voltage range : DC 0V to 10V
2. Input resistance : 22kΩ
Analog Input
AI2-GND
Analog input
terminal 2
1. Input range : DC 0V to 10V or
0/4mA~20mA, can be selected by J5 jumper
on main control board, default DC0V~10V
signal;
2. Input impedance: under voltage input-22
kΩ,
under current input 500Ω.

DI5-COM
Digital input
terminal 5
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%).
Digital Input
HDI1-COM
High speed
pulse input
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
