Features Broad Operating Temperature Range: Designed to withstand extreme temperatures, the delay on/off switch module operates seamlessly from -40°C to 85°C, making it suitable for both indoor and outdoor applications under harsh climatic conditions. Integrated LED Display: Featuring a clear and visible LED display, the timer relay module provides real-time information on the current settings and status, enabling users to easily adjust the delay time and monitor the system's operation without needing additional tools or displays. Constructed Materials: The delay timer switch relay module is built using reliable materials, ensuring stable performance and long service life in various environments. User-Friendly Operation: With a straightforward interface and intuitive controls, the timer switch module is exceptionally easy to set up and operate. Even for first-time users, configuring the timer to meet specific timing requirements is a breeze. Versatile Application Range: Due to its wide input voltage compatibility and advanced features, the adjustable timer module finds applications across a broad spectrum, including automation systems, security alarms, home appliances, industrial control circuits, and more. Specifications: Output Capacity: DC 5V~36V, at roomtemperature, continuous current is 15A, power 400W. With enhanced heatdissipation, the current can be up to 30A. Quiescent Current: 20mA Operating Current:50mA Working Temperature: -40℃~85℃ Clocking (Time Delay) Range: 0.1seconds to999minutes Size: 60*34*12mm / 2.36*1.33*0.47 Instruction: Operating Mode: P1: trigger signal, the relay is onOP time, and then disconnect; in the OP time, asfollows: P1.1: signal is triggered again, invalid P1.2: signal is triggered again, the clockingis reset P1.3: Signal is trigger again reset, relayoff, and stop the clocking P-2: trigger signal, the relay offCL of time, the relay on OP time, and then disconnectrelay after clocking P3.1: trigger signal, the relay is turnedon after the OP time, the relay off CL time, then theoperation cycles; if trigger signal again during the cycle, the relay off, stopclocking; the number of cycles times ( LOP ) can be set P3.2: without triggering signal after poweron, the relay is on OP time, the relay off CL time, thenthe operation cycles; the number of cycles times ( LOP ) can beset P-4: signal holding function. If there is triggersignal, clocking is reset, the relay remains on; when the signal disappears,after clocking OP time, the relay is off; if another signal istriggered during clocking, clocking will be reset How to Set Clocking Range: After setting the parameter value at modeselection, press STOP button to set the clocking range XXX.
