Green PCB relay module with black 9500 terminals and optocoupler isolation

Vszerda

Vszerda 1-Channel 5V Relay Module Optocoupler Isolated 30A 250V 9500 Terminals

SKU CH-ABHP-XRMHK

A single-channel 5 V relay module with optocoupler isolation and LED status indicator, switching loads up to 30 A at 250 V via 9500 terminals for PLC, IoT and home automation

  • Optocoupler isolation protects control circuits from load-side interference
  • High-power relay switches loads up to 30A at 250V AC
  • 9500 terminals simplify high-current wiring connections
  • LED indicator shows relay on/off status at a glance
  • Isolation slots separate control and load areas for safety

Single-Channel Relay Module for 5 V Logic

This single-channel 5 V relay module provides optocoupler isolation between the control signal and the load circuit. It is suited for PLC automation, industrial equipment control, IoT projects and home smart-control applications. The board accepts a DC 5 V supply that must match the relay coil voltage. Each channel includes an on-board LED indicator showing the relay state.

Double-Sided PCB with 9500 Terminals

A double-sided PCB layout separates the control area from the load area with isolation slots for improved anti-interference performance. Black 9500 terminals allow convenient high-current wiring up to the rated limits. The module handles load voltages of DC 30 V or AC 250 V at 30 A. An optocoupler on each channel protects the low-voltage side from transients on the switched circuit.

Upgrade from Basic Non-Isolated Switches

Builders moving from simple transistor or non-isolated relay boards gain galvanic isolation and visible status feedback with this module. The jump is worth it when the application demands reliable switching of 30 A loads and strong noise immunity in industrial or home-automation environments. It is not for designs requiring multiple independently controlled channels on a single board.
