Reliable programmable timer relay for automation, testing, and remote control Key benefits — why you need it Precise, repeatable timing for machines, sensors, and lights — removes guesswork from processes and testing. Wide input options let you integrate the relay into varied systems without extra converters. Robust switching and optocoupler isolation reduce false triggers from electrical noise and protect sensitive control electronics. Save three commonly used timing profiles to the device so setups are faster and consistent across runs. What it does and how it solves problems Flexible power and signal options: runs from DC 6–30 V and accepts USB 5 V input for easy connection to common power supplies or USB sources. This avoids the need for dedicated supply rails in many installations. Longrange timing: set intervals from 1 second up to 9,999 minutes for both short pulses and multihour cycles, covering most automation and test requirements without adding external timers. Persistent presets: the LCD displays current settings and stores up to three profiles so you can switch between jobs quickly and avoid repetitive reprogramming. Reliable flipflop control: supports both level and lowlevel flipflop modes for latching applications. Optocoupler insulation provides interference protection, and the design supports over 100,000 switching cycles for longterm operation. Standout attributes Function: programmable on/off timing, /low level flipflop latch modes, and profile memory for repeated tasks. Compatibility: DC 6–30 V main supply and USB 5 V connectivity for broad system integration. Performance: wide timer range (01 s to 9999 min), clear LCD readout, and robust switching life (over 100,000 cycles). Durability and signal integrity: optocoupler isolation minimizes electrical interference and protects control inputs and outputs. Form factor: compact, panelcompatible footprint for easy installation in control boxes or inline with existing equipment (no specific dimensions required). Practical use scenarios Production test bench: automatically apply timed power cycles to devices under test with saved profiles for different test stages, improving throughput and repeatability. Lighting and signage control: schedule short or long on/off cycles (from seconds to days) without a PLC; use flipflop mode to latch lights from a push button or sensor input. Irrigation or pump control: run pumps for precise durations and switch between preset watering cycles while protecting control electronics from noisy motor loads with optocoupler isolation. Quick technical summary Power input: DC 6–30 V; USB 5 V connectivity supported Timer range: 01 seconds to 9999 minutes Display and memory: LCD shows current settings; stores up to three profiles Modes: level and lowlevel flipflop modes Protection/performance: optocoupler insulation; over 100,000 switching cycles Use this programmable timer relay where consistent timing, electrical noise immunity, and simple profile switching are required for reliable automation and control.
