1 Channel Delay Power-off Relay Module with Cycle Timing Circuit Switch

A relay module with built-in timing logic, so it can switch a load on or off after a set delay or run a repeating on-off cycle without any microcontroller. Common in lighting timers, pump cycling, fan control and automatic shutdown circuits. Because it uses a mechanical relay it can switch AC as well as DC loads, unlike a MOSFET board. If switching mains, enclose it properly and treat it as electrical work. Timing built in, no microcontroller needed; Relay contacts switch AC or DC loads; Delay and repeating cycle modes; Screw terminals for solid load wiring
