UCTRONICS 12V Programmable Time Delay Relay Module — Metal Enclosure, 18 Modes, 0.1s–270h

UCTRONICS DC 12V Programmable Time Delay Relay Module is a compact, metal-enclosed timer relay that delivers 18 selectable working modes, adjustable delays from 0.1 seconds to 270 hours, and up to 10A switching for automotive, Raspberry Pi, or industrial control projects.

This programmable time-delay relay combines a durable metal housing with flexible timing functions to control circuits where delayed switching, pulse timing, or looped on/off sequences are needed. It accepts a 12V DC supply, tolerates loads up to DC 28V or AC 125V at 10A, and stores your configuration even after power loss. Reverse-polarity protection and clear terminal cutouts in the enclosure make it suitable for DIY electronics, vehicle modifications, and small automation tasks.

How do I set timing modes and ranges for my project?

Programming is done through the front-panel buttons and the display on the module; you can choose any of the 18 working modes, including on-delay, off-delay, pulse, and continuous loop options. Timing resolution runs from 0.1 seconds up to 270 hours, so the same module suits short pulses and long delays without extra hardware.

• 18 selectable modes: on/off delay, pulse, looped sequences, and more
• Delay range: 0.1s to 270h with button-adjustable steps
• Settings are saved automatically and retained after power loss
• Front-panel display and buttons for quick reprogramming

Will this relay handle automotive and Raspberry Pi outputs safely?

The module accepts a 12V DC supply and supports max load voltages up to DC 28V or AC 125V with a 10A maximum current, which covers many automotive accessories and small appliances. It also works well with PLC digital outputs and NPN/PNP sensor pulses, and the enclosure includes terminal cutouts that simplify wiring in cramped panels.

• Operating voltage: DC 12V; quiescent current 5.5mA
• Max load: DC 28V or AC 125V, up to 10A switching
• Compatible with PLC outputs and positive-voltage sensor signals
• Reverse-polarity protection reduces risk of damage during installation

How durable and installation-friendly is the metal enclosure?

The custom metal case protects the electronics while exposing only the display, buttons, and terminal blocks through precise cutouts for neat mounting. The enclosure resists impacts and provides a professional look for vehicle dashboards, control boxes, or wall-mounted projects.

• Custom-cut metal housing for display, buttons, LEDs, and terminals
• Screw terminals accessible from the enclosure for secure wiring
• Compact footprint suitable for dashboards, control cabinets, and hobby boxes
• LED indicators show relay state for quick visual verification

What safety and convenience features come with the timer?

Beyond automatic saving of settings and reverse-polarity protection, the unit provides predictable operation across repeated cycles and clear visual feedback so you know the relay state at a glance. These conveniences reduce setup time and help avoid interruptions caused by accidental power cuts.

• Auto-save of configuration prevents loss after power-off
• Reverse connection protection to prevent module damage
• Visible display and LEDs for instant status checks
• Suitable for repeated cycles and long-duration timing tasks

Who is this for? Engineers, makers, and technicians who need a reliable, programmable time-delay switch for automotive mods, Raspberry Pi or PLC projects, small industrial controls, LED lighting, motors, pumps, or sensor-based automation will find this UCTRONICS relay module a versatile component. It’s particularly useful when you want flexible timing modes, a protected metal enclosure, and settings that survive power interruptions without extra memory backup.
