The Story

4-Channel Optocoupler GPIO Relay Module, Single Unit
✔️ Dual trigger mode selectable: 3-24V high or 0-1.5V low, 5-32V input

This 4-channel optocoupler isolated GPIO relay module is built for robust automation in control panels, PLCs, and industrial equipment. It uses optical isolation to protect controllers and supports a wide input range for flexible wiring, making it ideal for harsh environments where fast, reliable switching matters.

✅ 4-channel GPIO relay with optocoupler isolation and NC/COM/NO contact layout
✅ Supports high level 3-24V and low level 0-1.5V triggering
✅ Wide power range 5-32V input with fast 10 ms response and up to 100,000 cycles
✅ Load ratings: NO 10A 250VAC, NC 5A 277VAC, 10A 28VDC
✅ Max switching power: NO 2770VA / 280W; NC 1250VA
✅ Copper-plated/tin-plated contacts (AgSnO2, AgCdO <100 ppm)
✅ DIN rail ABS housing for sturdy mounting and easy plug-and-play installation

💡 What is a handy use case for an optocoupled GPIO relay module in industrial automation? This handy answer highlights practical applications in a simple, scan-friendly format. - Use in control panels to switch mains devices safely - Isolate sensitive control electronics from load circuits - Quick plug-and-play with a 5-32V supply - Works with PLCs, microcontrollers, and automation projects
