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. Designed with 12V DC input voltage, it supports a load capacity of up to 30A 250VAC or 30A 30VDC. The module includes reverse polarity protection for power supply connection. It is widely used in timing control applications, household appliances, lighting delay circuits, industrial equipment, and time delay control systems. Specifications: - Time Delay Range: 0 seconds to 60 minutes (adjustable) - Time Delay Accuracy: <2% - Load Capacity: 30A 250VAC / 30A 30VDC - Operating Voltage: 12V DC - Dimensions: 82 x 35mm (3.22 x 1.37 inches) - Quantity: 1 piece Instructions: 1. Adjust the delay time by soldering the S1 to S5 jumpers according to the time delay chart. 2. When no jumpers are soldered, a trigger signal connects the output; a second trigger disconnects it. 3. The control signal is a momentary trigger type. Once triggered, the timing cycle proceeds independently of the signal state. 4. If re-triggered during an active delay period, the timer will reset and restart the delay cycle. 5. If the trigger terminals are shorted without a button, each power-up event acts as a single trigger input. Function 1: Power-on triggers immediate connection of the load; the load disconnects after the preset delay time. Method: Short the trigger terminals. Function 2: Power-on starts the delay period; the load connects automatically after the delay completes. Method: Short the trigger terminals and solder the S6 jumper. Package Includes: 1 x Timer Relay Module
