HW-516 Dual MOSFET Time Delay Cycle Timer Module – 5–36V DC

The HW-516 programmable timer module is a versatile solid-state controller for switching and timing DC loads such as motors, pumps, LED lighting, solenoids and other electronic equipment.

Unlike a conventional mechanical relay, the module uses dual MOSFET switching, providing fast, quiet operation with no relay clicking or contact wear.

Features:

• Operating voltage: 5–36V DC
• Dual MOSFET solid-state output
• Rated up to 15A / 400W under suitable operating conditions
• Trigger input: approximately 3–24V DC
• Adjustable timing from 0.1 seconds to 999 minutes
• Programmable delay ON and delay OFF functions
• Adjustable ON time and OFF time
• Repeating/cyclic operation
• Adjustable number of cycles or continuous looping
• External trigger input for sensors, switches or control circuits
• 3-digit LED display for programming and status
• Dedicated STOP, SET, UP and DOWN controls
• Emergency stop function
• Settings retained after power is removed
• Optocoupler-isolated trigger input for improved noise immunity
• Reverse-polarity protection
• No mechanical relay contacts, making it suitable for frequent switching applications

Ideal for:
DC motors, water pumps, fans, LED strips, solenoid valves, automatic watering systems, robotics, battery-powered equipment and DIY automation projects.

Typical functions include:
Delay before switching on, timed switch-off, automatic ON/OFF cycling, triggered operation and repeated timed sequences.

Model: HW-516
Supply: 5–36V DC
Timing range: 0.1 sec – 999 min
Output: Dual MOSFET, up to 15A / 400W
Trigger input: 3–24V DC

Note: This is a DC MOSFET switching module rather than an isolated mechanical relay. The output switches the connected DC supply and is not a volt-free/dry contact.
