12V Self-Lock Relay Timer Module for Arduino ESP32 PLC Projects

Key Highlights

• ✓Wide Voltage Compatibility: Supports DC 12V input control voltage. Can control AC (0-250V, max 10A) and DC (0-30V, max 10A). Relay Output Options: Normally Open (NO): The pin remains open before the relay closes and will connect with COM after the relay closes. Normally Closed (NC): Before the relay closes, the pin is connected to COM, and after the relay closes, it disconnects. Timer Functionality: Includes a self-locking relay cycle timer function that can delay the activation or deactivation of connected devices. High Current Handling: Maximum current rating of 10A, suitable for controlling large electrical loads like motors, lights, or other appliances. User-Friendly Control: Simple connection with DC control and signal input pin for easy integration into control systems. Durable and Reliable: Designed for PLC automation, the module is durable and reliable, ensuring stable operation for long-term use. Compact Size: Compact dimensions (6.5 x 4 cm / 2.6 x 1.6 inches) for easy integration into smaller control panels or projects. Protection Features: Reverse polarity protection to safeguard your system from damage due to incorrect connections. Cycle Timer: Enables the relay to cycle on/off with programmable delay functions for applications requiring periodic switching. Applications: Suitable for PLC automation, industrial control systems, lighting control, motor control, home automation systems, and more.
