Programmable Digital Timer Switch Relay Control DC 12V 24V AC 110V 220V Cycle Timing Microcomputer Controller

Automate your electrical devices, lighting, motors, and automated machinery with this Programmable Digital Time Controller Relay. Engineered for industrial, commercial, and DIY automation, this microcomputer-based timing switch offers broad voltage compatibility (DC 12V, DC 24V, AC 110V, and AC 220V options) to suit various control setups. Featuring customizable delay, loop, and infinite cycle timing modes, it allows you to configure exact ON and OFF operating intervals down to the second, minute, or hour. The dual high-definition LED display screen clearly shows set parameters alongside real-time countdowns. Compact, easy to wire, and built with reliable internal relay switching, this programmable microcomputer timer delivers precise, automated control over your pumps, fans, grow lights, and industrial equipment.

Key Features

• Multi-Voltage System Compatibility: Available in DC 12V, DC 24V, AC 110V, and AC 220V variants for seamless integration into diverse circuit configurations.

• Versatile Cycle & Delay Timing Modes: Supports single delay, intermittent looping, and infinite cycle timing functions with adjustable time units (seconds, minutes, hours).

• Dual HD LED Digital Display: Dual-color screen simultaneously displays preset target timing values and active live countdowns for effortless monitoring.

• Direct Relay Output Switching: Built-in heavy-duty relay output directly switches connected electrical loads up to maximum rated amperage.

• Internal Data Memory Protection: Retains all custom programmed timing modes and interval parameters during sudden power supply interruptions.

Why Choose Our Programmable Digital Time Controller

Simple analog timers and basic thermal relays lack dual-countdown displays, offer poor timing resolution, and drift out of sync over time. Single-function delay relays cannot handle complex infinite loop cycling, forcing you to chain multiple relays together for automated tasks like periodic venting or watering. This microcomputer digital timer combines multi-voltage options, flexible delay and infinite cycle modes, dual numerical LED displays, and internal memory retention—giving your equipment automation, grow room fans, and industrial control panels an instant professional upgrade.
