250VAC/30VDC 10A 5VDC 1-Channel Optocoupler Isolated LOW/HIGH Level Trigger Relay Module


In Stock
SKU: MYP-JHS-131 Categories: ,

This relay breakout board is not your average one. It features a single 5V activation relay capable of controlling 250VAC at 10A. There’s added isolation with an optocoupler for control, and you can configure the relay activation with a small jumper – either 5V (High) or 0V (Low).

It’s a user-friendly breakout board with one 5V-activated relay, equipped with three screw terminals for relay connections (NO, NC, COM) and screw terminals for control signals from microcontrollers like Arduino. The control signal is opto-isolated and protected, and there’s an activation LED indicator for the relay.
