3.4 Control terminal and function
| Category | Terminal Symbol | Terminal Name | Function Description |
|---|---|---|---|
| Power | +10V-GND | +10V Power | Provides +10V power externally, maximum output current: 20mA, typically used as the operating power supply for external potentiometers |
| Power | +24V-COM | +24V Power | Provides +24V power externally, maximum output current: 150mA, generally used as the power supply for digital input-output terminals and external sensor power |
| Power | OP | External Power Input Terminal | Connects to +24V or COM through the connection piece on the control board (factory default connection to +24V) When driving DI1~DI6 with external signals, OP needs to be connected to an external power source, and the short-circuit connection piece between OP and 24V should be removed |

| Analog Input | AI2-GND | Analog Input Terminal 2 | 1. Input Range: DC 0V~10V/0mA, selected by parameter P4-37 for voltage or current input. 2. Input Impedance: 22kΩ for voltage input, 500Ω for current input |
| Digital Input | X1, X2, X3, X4, X5, X6, X7 | Digital Input 1, 2, 3, 4, 5, 6, 7 | 1. Opto-isolation 2. Input Impedance: 4kΩ Input Voltage Range: 9V~30V |
| Analog Output | AO1-GND | Analog Output 1 | AO1, AO2 are selected for voltage or current output by jumpers J3 and J2 on the control board Output Voltage Range: 0V~10V Output Current Range: 0mA~20mA Factory default is voltage output |
| Analog Output | AO2-GND (shared with Y1 for models below 18.5kW, selected by jumpers) | Analog Output 2 | AO1, AO2 are selected for voltage or current output by jumpers J3 and J2 on the control board Output Voltage Range: 0V~10V Output Current Range: 0mA~20mA Factory default is voltage output |
| Digital Output | HD0 | High-Speed Pulse Output Collector-Emitter Open Circuit Output | 1. Opto-isolation, bipolar open circuit collector output. 2. Output Voltage Range: 0V~24V Output Current Range: 0mA~50mA (Note: For models of 18.5kW and below, Y1 function can be switched to analog output by jumpers) |
| Digital Output | Y1 | Digital Output 1 Analog Voltage Output 2 | 1. Opto-isolation, bipolar open circuit collector output. 2. Output Voltage Range: 0V~24V Output Current Range: 0mA~50mA (Note: For models of 18.5kW and below, Y1 function can be switched to analog output by jumpers) |
