NE555 Delay Timer Relay Module – Adjustable 0-10 Second Power-On Delay Switch for Automotive, DIY Electronics, and Industrial Sequencing

Product Description

The NE555 Delay Timer Relay Module is a robust and versatile timing solution designed to introduce a precise power-on delay into your circuits. Built around the classic NE555 timer IC, this module allows you to prevent electrical surges, sequence industrial machinery, or create custom automotive lighting delays. When 12V power is applied to the module, the timer begins; once the set delay is reached, the relay triggers, closing (or opening) your secondary circuit. At Robogears, we recommend this module for its high-current handling capabilities and its "set-and-forget" reliability in both hobbyist and industrial environments in Pimpri.

Detailed Key Features

• Precision NE555 Timing: Utilizes the industry-standard NE555 chip to provide consistent and repeatable timing cycles.

• Adjustable Delay Range: Features an onboard multi-turn potentiometer, allowing you to fine-tune the delay from near-instantaneous up to 10 seconds.

• High-Current Relay: Equipped with a genuine 10A relay capable of switching high-power AC appliances or heavy-duty DC motors.

• Dual Output Configuration: Provides both Normally Open (NO) and Normally Closed (NC) terminals, giving you flexibility for "Delay-On" or "Delay-Off" applications.

• LED Status Indicators: Includes a power LED (Red) and a relay status LED (Green) for instant visual feedback during operation.

All Technical Details

• Trigger Mechanism: Power-on reset (timing starts immediately upon 12V input).

• Terminal Blocks: Features secure screw-type terminals for easy wiring without the need for specialized connectors.

• Protection Circuitry: Includes a flyback diode across the relay coil to protect the NE555 chip from inductive voltage spikes.

• Mounting Holes: The PCB includes two mounting holes for secure installation inside project boxes or control panels.
