Features: This timer relay module offers high precision, stable, and reliable performance. It provides a wide range of adjustable delay times, which can be set by soldering the S1 to S5 jumper connections. The module operates on 12V DC input voltage and supports a load capacity of up to 30A 250VAC or 30A 30VDC. It includes reverse polarity protection for power supply connection. Ideal for use in timing control equipment, household appliances, lighting delay circuits, industrial machinery, and time delay applications. Specifications: - Time Delay Range: 0 seconds to 60 minutes (adjustable) - Time Delay Accuracy: <2% - Load Capacity: 30A 250VAC / 30A 30VDC - Dimensions: 82 x 35mm (3.22 x 1.37 inches) - Quantity: 1 piece Instructions: 1. Solder the S1 to S5 jumper connections according to the delay time table to set the desired delay. 2. When no jumpers are soldered, a trigger signal connects the output; a second trigger disconnects it. 3. The control signal is trigger-based. Once triggered, the timing cycle proceeds regardless of signal maintenance or removal. 4. If triggered again during an active delay period, the timer restarts from the beginning. 5. If the trigger terminals are shorted without a button, each power-up event acts as one trigger input. Function 1: Power-on activates the load immediately; load disconnects after the preset delay. Method: Short the trigger terminals. Function 2: Power-on starts the delay period; load connects after the delay completes. Method: Short the trigger terminals and solder the S6 jumper. Package Includes: 1 x Timer Relay Module
