Cycle Time – 2 Output is a microcontroller-based cyclic ON/OFF timer designed to operate two loads cyclically in a fully automatic manner. It ensures that only one output runs at a time, while the second output remains on standby, helping to reduce electrical load, save energy, and extend equipment life.
The controller features a bright digital LED display, simple push-button programming, and two independent relay outputs, making it reliable, easy to operate, and ideal for continuous-duty applications.
Working Principle:
- Power Supply
- Operates on single-phase 220 V AC.
- Sequential / Cyclic Operation
- Output-1 turns ON for a programmed time.
- After its ON time completes, Output-1 turns OFF.
- Output-2 then turns ON for its programmed duration.
- After its ON time completes, Output-2 turns OFF.
- This sequence repeats continuously in cyclic mode.
- Microcontroller Accuracy
- A built-in microcontroller ensures precise timing, consistent switching, and long-term reliability without drift.
- User Programming
- Three push buttons allow easy setting of ON/OFF times.
- The digital display shows time values and output LEDs show the operating status clearly.
- Relay Outputs
- Both outputs are potential-free relay contacts.
- During ON time, the relay contact closes, allowing the phase line to pass to the connected Output.
- Neutral remains common and is not switched.
- AUTO / BYPASS Mode
- AUTO Mode: Fully automatic cyclic operation.
- BYPASS Mode: Simultaneously turns ON both outputs.
