Category	Terminal symbol	Terminal name	Function description
Power supply	+10V-GND	External connection of ＋10V power supply	Provide power supply of +10V externally, with maximize output current: 10mA It is generally used as working power supply for external potentiometer and the resistance range of potentiometer is 1kΩ~5k Ω
	+24V-COM	External connection of ＋24V power supply	+24V power supply is provided outwards and generally used as the working power supply for digital input/output terminal and the power supply for external sensor Maximum output current: 200mA
	OP	Input terminal of external power supply	The factory default is connection to＋24V When an external signal is used to drive DI1~DI7, OP shall be connected to external power supply and disconnected from＋24V power supply terminal
Analog input	AI1-GND	Analog Input Terminal 1	1. Input voltage range: DC 0V~10V 2. Input resistance: 22kΩ
	AI2-GND	Analog Input Terminal 2	1. Input range: DC 0V~10V/4mA~20mA, as determined by Jumper J8 on the control panel 2. Input resistance: 22kΩ for voltage input and 500Ω for current input.
Digital input	DI1- OP	Digital Input 1	1. Optical coupler isolation, with bipolar input 2. Input resistance: 2.4kΩ 3. Voltage range in input level: 9V~30V
	DI2- OP	Digital Input 2
	DI3- OP	Digital Input 3
	DI4- OP	Digital Input 4
	DI6- OP	Digital Input 6
	DI7- OP	Digital Input 7
	DI5- OP	High-speed pulse input terminal	Apart from the characteristics of DI1~DI7, it may be used as high-speed pulse input channel. Maximum input frequency: 100kHz
Analog output	AO1-GND	Analog Output 1	Jumper J5 on the control panel shall determine voltage or current output. Output voltage range: 0V~10V Output current range: 0mA~20mA
Digital output	DO1-CME	Digital Output 1	Optical coupler isolation, bipolar open collector output Output voltage range: 0V~24V Output current range: 0mA~50mA Note: Digital output CME is internally separated from digital input COM, but CME and COM have been short-circuited externally in delivery (At this moment, DO1 default is ＋24V drive). When DO1 is driven by external power supply, it is necessary to cut off the external short circuit between CME and COM
	FM- COM	High-speed pulse output	Function code F5-00 “FM terminal output mode” can be used as high-speed pulse output and maximum frequency can reach 100kHz; the high-speed pulse output can be used as pen collector output and is identical with DO1 specification.
Relay output	T/A-T/B	Closed terminal	Contact drive capacity: 25V ac，3A，COSØ=0.4 。 30Vdc ，1A
	T/A-T/C	Open terminal
Secondary interface	J12	Interface for IO expansion card	28-core terminal, the interface for optional I/O expansion card
	J3	Interface for PG card	Options: OC, difference, rotary conversion and other interfaces
	J7	External keyboard interface	External keyboard
Communication interface	485+，485-	Modbus	Modbus communication interface, non-isolated output
