Function Description
Power
Supply
+10V~
GND
Ex10V
power
P10V power supply for external units, and the
maximum output current is 10mA.
It is generally used as the operating power supply for the
external potentiometer. The potentiometer resistance range
is 1kΩ~5kΩ.
+24V~
COM
Ex24V
power
P24V power supply for external units. It is generally
used as the operating power supply for digital input/output
terminals and the external sensor.
The maximum output current is 200mA.
PLC
External power
input terminal
Connect to 24V by default upon delivery
When external signal is used to drive D1 ~ D6, and HDI,
PLC needs to connect to the external power supply and
disconnect from the +24V power terminal
Analog
Input
AI1~GND
Analog input
terminal 1
1. Input range: DC 0V~10V/4mA~20mA, determined by J1
jumper on the control board.
2. Input impedance: 20
kΩ (voltage); 500Ω(current)
AI2~GND
Analog input
terminal 2
1. Input range: DC 0V~10V/4mA~20mA, determined by J2
jumper on the control board.
2. Input impedance: 20
kΩ (voltage); 500Ω(current)
Digital
Input
D1
Digital input 1
1. Optical coupling isolation, compatible with dual polarity
input
2. Input impedance: 4.7kΩ
3. Voltage range for level input: 9V ~30V
D2
Digital input 2
D3
Digital input 3
D4
Digital input 4
D5
Digital input 5
D6
Digital input 6
HDI~CME/
D7~COM
High-speed pulse
input terminal
In addition to the characteristics of D1 to D6, it can also be
used as the high speed pulse input channel.
Maximum input frequency is 100kHz
Caution: The CME is internally insulated with the COM, but
they have been short circuited externally (HDI is driven by
+24V by default prior to delivery). When HDI needs to be
driven by the external power, the short circuited between
CME and COM must be disconnected.
Analog
Output
AO1~GND
Analog output 1
The voltage or current output is determined by J3 jumper on
the control board.
Output voltage range: 0V~10V. Output current range: 0mA~
20mA.
AO2~GND
Analog output 2
The voltage or current output is determined by J4 jumper on
the control board.
Output voltage range: 0V~10V. Output current range: 0mA~
20mA.
