Compact High-Level SSR Module for Fast, Quiet Switching
The 1 Channel 5V High Level Trigger Solid State Relay Module is a compact SSR board for projects that need silent, fast, and durable switching in a small footprint. It is designed for high-level trigger control and is useful for many precise switching jobs where mechanical relay noise is not wanted.
Its board-level format, terminal blocks, and mounting holes make it easy to place in custom enclosures, test rigs, and embedded control projects.
Important: This listing describes a high-level trigger SSR board with board-level wiring features. Make sure the control threshold and the target load type match your application before use.
Why you'll like it
- High-level trigger: Easy logic-side control in many systems
- Solid-state switching: Quiet and long-lasting
- Up to 5A class output: Useful for compact switching tasks
- Terminal block wiring: Faster installation and servicing
- Mounting holes included: Easy board installation
What you can build
Use it for compact DC switching, controller outputs, embedded boxes, test benches, and projects that need quiet switching and easy mounting.
Starter bundles
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus jumper wires, a suitable power supply, and a small load for bench testing.
Recommended add-ons
Useful add-ons include terminal block, breadboard, power modules, fuses, and enclosure, especially when you are working with higher voltages or inductive loads.

Pinout & power notes
Apply the logic-side control to the trigger input and wire the target load through the SSR output side. Because board revisions can vary, confirm the exact terminal labels before powering the module.
