Configurable Jumper Design: Equipped with a configurable jumper, allowing users to set the relay module to change states with either a high or low signal. This module includes terminals for easy installation of relay (NC, C, NO) and input (Coil +, Coil -, and Trigger). 12V Relay Module Specifications: Operates on DC 12V with a maximum load capacity of AC 250V/10A or DC 30V/10A. The trigger current required for the -isolator is just 5mA, making it highly efficient for various applications. Optocoupler Isolation for Safety: Features a 1-channel relay board with optocoupler isolation to enhance driving capabilities and stable performance. This isolation helps prevent any potential damage to I/O ports from relay switch currents, enhancing device . Enhanced Fault-Tolerance: Designed with robust fault tolerance, ensuring that even if the control line is disrupted, the relay remain non-operational. All connection interfaces can be directly wired through accessible terminals, offering configurations for normally open and normally closed setups. Versatile Compatibility: This DC 12V relay module is compatible with a wide range of Microcontrollers and systems including ARM, PIC, AVR, MCU, , CNC machines, and . Its versatility makes it ideal for various industrial and hobbyist applications., Weight: 1.5211896078 pounds, Manufacturer: Kueohse
