4-Channel Programmable Relay Module 6-24V DC Trigger Delay Timer & Motor Reversing Controller

The ShillehTek 4CH Programmable Relay Module is a compact 4-channel relay board built for automation, remote switching, and multi-load control projects. Powered from a wide DC 6 to 24V input, it’s easy to drop into control boxes, benchtop prototypes, and DIY builds where you need reliable switching for lights, pumps, fans, solenoids, and other loads (within relay ratings). With four independent channels and isolation between control and load side, it’s a practical choice for home automation, robotics, test rigs, and maker projects that need clean wiring and repeatable results.
