The simplest way to automate sequences of lights, solenoids, fans, and motors — no programming required. Record once, replay forever.
Program with switches. No computer or software required — just record and playback.
Works with 7–24V AC or 7–30V DC. Reverse-polarity proof on power input.
Four relays with 10A @ 250VAC or 30VDC contact rating. NO and NC contacts.
Use one module to trigger up to four more for multi-zone sequence control.
Relay Replay is a board that can control anything that can be turned on and off with a switch. Typical applications include holiday light coordination, animated displays, solenoid control, fan automation, and sound systems.
After wiring it up, the only tool you may need is a ballpoint pen or small screwdriver to move the switches for setting the mode or enabling write protection. To trigger the sequence, simply connect the trigger wire to the ground wire — it will start playing back.
A regulated 5V output is available to power small motion sensors or other trigger electronics. Uses hardware pullups and debouncing for electrically noisy environments.
