Heavy Duty 5V 30A Single Channel Relay Module With Optocoupler Isolation And High Low Level Trigger For Industrial Control Applications Handles AC 250V 30A Or DC 30V 30A Loads And Delivers 100000 Plus Switching Cycles

Heavy-Duty 5V Relay Module with Optocoupler Isolation
✔️ 30A AC/DC switching, optocoupler isolation, 5V coil; 2-module pack

This heavy-duty relay module is designed for industrial control apps. It handles AC 250V 30A or DC 30V 30A loads and uses optocoupler isolation to protect control circuitry. Typical uses include automation panels, machine controls, motor control, and robotics projects.

✅ 30A heavy-duty switching supports AC 250V/30A or DC 30V/30A loads (3,750W max) with silver-alloy contacts and 100,000+ cycles.
✅ Optocoupler isolation with jumper-selectable high/low level trigger (3,750Vrms protection) and 2-4mA signal current.
✅ 5V coil (190mA max), quiescent current 5mA, compatible with Arduino/PLC outputs.
✅ Industrial screw-terminal design for NO/COM/NC outputs (12-10AWG) and IN/DC+/DC- control inputs.
✅ 2-Module Value Pack: identical 5V relay modules for parallel high-current applications.

💡 What is a 5V relay module with optocoupler isolation used for in industrial automation?

This handy module lets you control high-current loads from low-voltage controllers, while keeping the control circuit isolated for safety and reliability.

1) Interfaces Arduino, PLCs, or microcontrollers with AC loads up to 250V/30A or DC loads up to 30V/30A. 2) Optocoupler isolation reduces noise and protects logic from power surges. 3) 5V coil with low quiescent current fits common 5V logic boards and microcontrollers. 4) Durable screw-terminal design supports wiring with 12-10 AWG for solid connections.
