Terminals of main control board
Terminal Terminal Name Description
+10V-GND
+10 VDC power supply
Provide +10 VDC power supply externally. Usually, it provides power
supply to the external potentiometer with resistance range of 1 to
Max. output current: 10 mA.
+24V-COM +24 VDC power supply
Provide +24 VDC power supply externally. Usually, it provides power
supply to DI/DO terminals and external sensors.
Max. output current: 200 mA.
OP Input terminal of external power supply
Connect to +24 VDC by default.
Whether it connects to +24 V or COM is
When DI1 to DI5 need to be driven by the external
signal, OP needs to be connected to the external power supply and be
disconnected from +24 VDC.
AI1-GND Analog input 1
AI1 input voltage range: 0 to 10 VDC.
Impedance: 22
AI2-GND Analog input 2
AI2 can be used as voltage input or current input, which is chosen by
jumper J8 on main control card.
Input range: 0 to 10 VDC or 4 to 20 mA.
Impedance: 22 if voltage input, 500 if current input.
DI1-COM Digital input 1
Optical coupling isolation, compatible with dual-polarity input.
Input voltage range: 9 to 30 VDC.
DI2-COM Digital input 2
DI3-COM Digital input 3
DI4-COM Digital input 4
DI5-COM High-speed pulse input
Besides features of DI1 to DI4, it can be used for high-
Max. input frequency: 100 kHz.
AO1-GND Analog output 1
Voltage or current output, determined by jumper J5 on main control
Output voltage range: 0 to 10 VDC.
Output current range: 0 to 20 mA.
DO1-CME Digital output 1
Open-collector, dual polarity output, optical coupling isolated.
Voltage range: 0 to 24 VDC.
Current range: 0 to 50 mA.
FM-COM High-speed pulse output
t is restricted by F5-00 (FM terminal output mode selection).
As a high-speed pulse output, the maximum frequency is 100 kHz.
As an open-collector output, its specification is the same as that of DO1
Voltage range: 0 to 24 VDC.
Current range: 0 to 50 mA.
T/A-T/B Normally closed terminal Contact driving capacity:
250 VAC, 3 A; 30 VDC, 1 A.
T/A-T/C Normally open terminal
