Relay Module 1 Channel 12V with High/Low Level Trigger Selector

Description

Relay Module 1 Channel 12V with High/Low Level Trigger Selector The Relay Module 1 Channel 12V with High/Low Level Trigger Selector is a highly reliable and versatile switching device designed to control high-voltage and high-current circuits using low-voltage control signals. Operating at 12V DC, this single-channel module is ideal for integration with microcontrollers, such as Arduino or Raspberry Pi, or other digital control systems requiring precise control of high-power loads. Its robust design and user-friendly features make it an excellent choice for technical writers documenting electronics projects for e-commerce platforms, catering to both hobbyists and professional engineers. Features: Normally open and Normally closed. High-level trigger or low-Level trigger selection by a jumper. Optocoupler isolation. Terminal blocks for both input and output. Two LED indicators: power (green LED), the relay status (red LED). Fault-tolerant design, even if the control line is broken, the relay will not operate. Specifications: Parameter Value Supply Voltage 12VDC Relay Type SPDT (NO, COM, NC) Relay Rating 10A @ 250VAC / 30VDC Trigger Current 3mA ~ 5mA. Dimensions(LxWxH) 48mm x 25mm x 18.5mm Coil Voltage 12V Input Interface: DC+ : Connect the positive pole of the power supply. DC- : Connected the negative pole of the power supply. IN: Signal trigger input ( high or low level signal selected via a jumper). Output Interface: NO: The normally open interface. NC: The normally closed interface. COM: The common interface for both normally open and normally closed. High/Low level Trigger Selection Jumper: If the jumper is placed between COM and L, the relay uses LOW level trigger. If the jumper is placed between COM and H, the relay uses HIGH level trigger. How it works High Level Trigger: When IN is LOW level signal, the NO does not connect with COM and the NC connects with COM. When IN is HIGH level signal, the NO connects with COM and the NC does not connect with COM. Low Level Trigger: When IN is LOW level signal, the NO connects with COM and the NC does not connect with COM. When IN is HIGH level signal, the NO does not connect with COM and the NC connects with COM. Applications: Home automation systems for controlling lights, fans, and appliances. Industrial control systems for switching machinery and equipment. Automotive electronics for managing car accessories and systems. Security systems for alarm triggers and access control. 3D printing: Auto shut-down for printers like Prusa i3 Mk2S, triggered by hotend fan power to shut off when the hotend cools below a set temperature. package Include: 1 x Relay Module 1 Channel 12V with High/Low Level Trigger Selector.
