Symmetrical Recycling Timers – Cyclic On/Off Timing for Automation
Symmetrical Recycling Timers
Symmetrical Recycling Timers are cyclic time delay relays that repeatedly switch the output on and off for equal time periods. Designed for automation, signalling, and process applications, these timers ensure consistent cycle timing for tasks such as flashing indicators, dosing pumps, and periodic control sequences.
🔧 Technical Highlights:
- Function: Alternating on/off timing with equal (symmetrical) durations for continuous or controlled cyclic operation.
- Supply Range: Universal 12–240 V AC/DC input for flexible integration.
- Timing Range: Adjustable from milliseconds to hours, depending on model and application.
- Outputs: SPCO or DPCO relay contacts; solid-state outputs available for silent operation and long life.
- Modes: Start with ON or OFF cycle selectable on most models.
- Indicators: LED display for power, timing, and relay status.
- Mounting: 35 mm DIN rail or panel mount format.
- Compliance: CE and RoHS; UL/CSA models available for export or OEM panels.
✅ Benefits:
- Provides accurate, repeating timing for cyclic processes.
- Reduces need for external control circuits or PLC programming.
- Universal supply simplifies installation and spares stocking.
- Ideal for continuous or periodic automation control tasks.
- Reliable design suited to industrial, process, and building systems.
🚀 Applications:
- Flashing beacons, tower lights, and warning indicators.
- Dosing pumps and solenoid valve cycling.
- Periodic testing or ventilation control systems.
- Conveyor pulse control and machine sequence cycling.
- Alternating systems requiring regular duty intervals.
Symmetrical recycling timers deliver stable, repeating on/off control for continuous process automation and visual or mechanical signalling applications.

FAQs
- Q: What is the difference between symmetrical and asymmetrical recycling timers?
A: Symmetrical timers have equal on and off durations, while asymmetrical timers allow independent adjustment of each period.
- Q: Can symmetrical recycling timers start with the output on or off?
A: Yes, most models allow selection of the starting state (ON or OFF) via front switch or configuration jumper.
