This set of 2 digital time delay relay modules features a clear LCD display and a DC voltage range of 6-30V, offering timer accuracy from 0.01 seconds to 9999 minutes for your automation projects. This device is designed with an industrial-grade circuit board and optocoupler isolation, ensuring reliable electrical load management in a variety of environments. Intuitive LCD display: The backlit screen shows real-time relay status, current operating mode, countdown status, and remaining time, allowing for instant visual monitoring without external equipment. Trigger flexibility: The module accepts three distinct input signal types, including high level (3.0V-24V), low level (0.0V-0.2V), and passive switch control, making it compatible with most existing sensors and control systems. Advanced power management: With an intelligent sleep mode, the device automatically reduces power consumption after 5 minutes of inactivity by turning off the backlight, while allowing instant wake-up with a simple press of any key on the panel. Safety and memory: The design includes reverse polarity protection to prevent damage during incorrect wiring, while the power-off storage function ensures that all your customized settings (OP, CL, LOP) are permanently saved even in the event of a power outage.
