A versatile, compact relay board that can drive up to 10A @28VDC while only drawing approximately 60mA at 5V.

A versatile relay board with opto-isolated inputs. Each channel can switch up to 10A @28VDC





Securely control inductive loads and execute complex automated logic directly from the edge. The Waveshare ESP32-S3-ETH-8DI-8RO-C integrates eight isolated 10A relays, an onboard CAN interface, and robust dual-core processing into a DIN-rail enclosure.

Safely control circuits and isolate logic inputs. Driven by an ESP32-S3, this DIN-rail mountable hub features robust optocoupler isolation and comprehensive connectivity, including RS485.




Z-Wave relay with two NO/NC outputs and dual dry-contact 12-24V inputs to control DC up/down motors, sprinklers and gates.






Single-channel WisBlock relay switches up to 250 VAC/10 A for control of motors, lights and conveyors in IoT projects.



Bring programmable switching to a DIN rail - high-power relays, isolated field inputs and a wired network connection in one unit.







Your 5V system can wield great power with this big, beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!

Industrial-grade switching for DIN-rail panels, controlled over Ethernet and powered from the same cable via POE.


Six independently controlled relay channels in one compact enclosure, driven by a Seeed Studio XIAO ESP32-C6 with ESPHome firmware pre-installed.






DIN rail mount for DPDT Relays with screw terminals.
