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.


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.

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


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







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







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!

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












This breakout module gives you access to a 8 channel solid state relay that can be switched with 3-5VDC

This is the 915MHz base RFM69HCW Wireless Transceiver that is found on Sparkfuns RFM69 Breakout. The RFM69HCW is an inexpensive and versatile radio module that operates in the unlicensed ISM (Industry, Science and Medicine) band, a set of frequencies set aside for low-power, short-range, license-free radios.

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



This breakout module gives you access to a 2 channel solid state relay that can be switched with 3-5VDC

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