YYB5 Time Relay Controller Flexible timing options with adjustable delay and multiple modes (ondelay, offdelay, interval, pulse) for precise control of electrical loads and sequences. Compact and reliable: small module designed for easy integration into control panels or projects; built with robust components for dependable operation. Wide compatibility: works with standard control signals and common electrical loads; easy to interface with PLCs, microcontrollers, and home automation systems. Precise and consistent performance: low drift timing, stable switching, and long service life for repetitive tasks. Clear benefits: reduces manual timing work, improves accuracy, and simplifies automation projects. Use scenarios: 1) Home automation: schedule lights, fans, or outlets to turn on/off at set times. 2) Irrigation control: run pumps or solenoid valves for exact durations and intervals. 3) Industrial automation: timesequenced control for conveyors, sensors, or test rigs.
