Overview

Product Overview

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.

Questions & answers

Frequently asked questions

It can be used with controllers or systems that provide the required 6–24V DC power and compatible trigger wiring. Do not assume direct GPIO drive from Arduino, Raspberry Pi, or ESP32 unless the input requirements are matched safely.
Yes. This ShillehTek board is sold pre-soldered, so it is ready for wiring into a prototype, control box, or DIY build. You still need to connect the DC supply, trigger inputs, and external loads correctly.
The module is powered from a DC input in the 6–24V range. The relay load side is separate from the control side, and any connected device must stay within the relay’s rated switching limits.
Yes. The four independent relay channels can switch multiple loads such as lights, pumps, fans, solenoids, and similar devices when they are within relay ratings. It suits home automation, robotics, test rigs, and remote switching projects.
Check that the DC supply is within 6–24V, the trigger wiring is correct, and the load is connected to the proper relay contacts. Also confirm the load is within relay ratings and the control/load sides are not miswired.
