This digital cyclic timer is a robust digital timer designed for precision ON/OFF control in industrial, automation, and equipment timing applications. It also functions as a reliable cyclic timer and countdown timer for repetitive time-based switching tasks.
Powered by 230V AC and built around a high-accuracy PIC MCU, this timer lets you set ON and OFF durations with simple buttons (SET, INC, DEC). The built-in relay switches 230V AC up to 10 A, making it ideal for motors, heaters, pumps, lights, and other loads.
⚠️ Note: This timer is not RTC (Real-Time Clock) based it measures elapsed timing, not clock time.

Problems This Timer Solves
❗ Problem: Manual control of equipment leads to inconsistent operation and wasted energy.
✔️ Solution: Set precise ON/OFF cycles with this digital timer to automate control and ensure repeatable performance.
❗ Problem: After power loss, many timers reset and require reprogramming.
✔️ Solution: This cyclic timer retains settings automatically — no need to re-enter times after power is restored.
❗ Problem: You need periodic switching that standard delays don’t support.
✔️ Solution: Use the On-Off Cyclic and Off-On Cyclic modes for repetitive cycles without external controllers.
Typical Applications
- Automated switching of motors, pumps, compressors
- Lighting control (periodic ON/OFF schedules)
- Industrial process timing
- Conveyor, batching, or dosing systems
- Fan and HVAC automation
- Agricultural irrigation cycles
