4.6.2 Control circuit terminals
Terminal Description
S1~S5
ON-OFF signal input, optical coupling with PW and COM.
Input voltage range: 9~30V
Input impedance: 3.3kΩ
HDI1（HDI2）
High speed pulse or ON-OFF signal input, optical coupling with
PW and COM.
Pulse input frequency range: 0~50kHz
Input voltage range: 9~30V
Input impedance: 1.1kΩ
PW
External power supply. +24V terminal is connected to PW
terminal as default setting. If user need external power supply,
disconnect +24V terminal with PW terminal and connect PW
terminal with external power supply.
+24V
Provide output power supply of +24V.
Maximum output current: 150mA
AI1（AI3，AI4）
Analog input, 0~10V
Input impedance: 10kΩ
AI2
Analog input, 0~10V/ 0~20mA, switched by J18.
Input impedance:10kΩ (voltage input) / 250Ω (current input)
GND
Common ground terminal of analog signal and +10V.
GND must isolated from COM.
Y1（Y2）
Open collector output terminal, the corresponding common
ground terminal is CME.
External voltage range: 0~24V
Output current range: 0~50mA
CME Common terminal of open collector output
COM
Common ground terminal for digital signal and +24V (or external
power supply).
+10V Supply +10V for inverter.
HDO
High speed pulse output terminal. The corresponding common
ground terminal is COM.
Output frequency range: 0~50 kHz
AO1（AO2）
Provide voltage or current output which can be switched by J19.
Output range: 0~10V/ 0~20mA
PE Ground Terminal.
