The RCT/D Microprocessor-Based Repeat Cycle Timer Relay, developed by Borna Electronics, is designed for applications requiring continuous ON/OFF cycling of electrical equipment and control circuits. Typical applications include misting systems, lubrication systems, irrigation panels, industrial automation, and process control systems.
By utilizing advanced microprocessor technology, the RCT/D provides significantly improved timing accuracy compared to conventional analog repeat cycle timers. The relay allows independent adjustment of ON and OFF periods, making it suitable for precise duty cycle control and repetitive switching applications.
Features
- Continuous ON/OFF cycling operation (Flip-Flop mode)
- Time base selection switch for seconds or minutes
- Independent adjustment of ON and OFF times
- Adjustable duty cycle control
- Suitable for flasher applications
- Operation starts with OFF time
- Two LED indicators: OFF (OFF timing status) and ON (ON timing status)
- Microprocessor-based timing for improved accuracy
