The module adopts genuine high-quality relays, normally open interface maximum load: AC 250V/10A, DC 30V/10A _x005f_x000D_ 2. The use of SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA _x005f_x000D_ 3. Module operating voltage 5V12V24V _x005f_x000D_ 4. The module can be set through the jumper high level or low level trigger _x005f_x000D_ 5. Fault-tolerant design, even if the control line is broken, the relay will not act;     _x005f_x000D_ 6. Power indicator (green), relay status indicator (red) _x005f_x000D_ 7. Interface design humanization, all interfaces can be directly connected through the terminal leads, very convenient! _x005f_x000D_ Module Interface: _x005f_x000D_ 1. DC +: connected to the positive pole of the power supply (voltage according to the requirements of the relay) _x005f_x000D_ 2. DC-: connected to the negative pole of the power supply _x005f_x000D_ 3. IN: can be high or low level control relay suction _x005f_x000D_ Relay Output: _x005f_x000D_ 1. NO: Normally-open relay interface, the relay is suspended before the relay is engaged, and is shorted to COM after the relay is engaged. _x005f_x000D_ 2. COM: relay common interface _x005f_x000D_ 3. NC: Normally closed relay interface, shorted to COM before the relay is engaged, and suspended after the relay is engaged. _x005f_x000D_ High and low level trigger selection terminal: _x005f_x000D_ 1. When the jumper is shorted to LOW, it is triggered by low level. _x005f_x000D_ 2. When the jumper is shorted to HIGH, it is triggered at high level. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1*High/Low Level Trigger Relay Module 1.Stable Performance: This high/low level trigger relay module ensures reliable and stable operation, making it suitable for various applications where consistent performance is crucial. 2.High Driving Capability: With its strong driving capability, this high low level trigger board effectively controls the relay, allowing for efficient and effective switching of electrical circuits. 3.Optocoupler Isolation: The high and low level relay module utilizes optocoupler isolation, providing increased stability and preventing interference between the input and output signals. It ensures safer and more reliable operation. 4.Fault-Tolerant Design: Even if the control line is disconnected, the relay module board shield will not be triggered unintentionally, thanks to the module's fault-tolerant design. This feature ensures the system remains secure and prevents accidental malfunctions. 5.User-Friendly Interface: The high low level trigger relay switch features a humanized interface design, allowing easy connection with external devices using terminal blocks. The power indicator (green) and relay status indicator (red) provide clear visual feedback.
