8 Channel 5V Relay Module

Beyond two or three relays, a project's home automation or industrial control needs usually call for switching several devices independently from one board rather than wiring individual relay modules one at a time. This module puts eight relays on one board, each rated for 250V AC or 30V DC at 10A - genuine mains-switching capacity, not a signal-level relay - triggered by a low 5mA current that any microcontroller pin can supply directly.

Each channel switches independently, so a project can control eight separate devices - lights, pumps, appliances - from eight digital output pins, with each relay's state completely independent of the others. The wide -40C to 85C operating range means it tolerates outdoor or unconditioned enclosure installations that a consumer-grade relay might not.

Standard board for home automation systems controlling multiple appliances, industrial control panels switching several loads, and any project needing more independent mains-switching channels than a 1 or 2-relay module provides.
