Product description: IoTPi - 6-channel RS485 relay module RP2040 + ESP8266 WiFi - SB Components SKU24179
IoTPi is equipped with 6 relays galvanically separated from the control system . The module from SB Components is based on the RP2040 microcontroller enabling communication via the RS485 protocol and the ESP8266 system, which is responsible for WiFi communication. Thanks to the WiFi module, it is possible to create a simple system allowing remote control of electrical devices or lighting. The relays used in IoTPi support a load of up to 10 A for 230 V AC and 30 V DC . The EL357NC optocoupler enables safe regulation of high voltages or currents. The module can also be controlled using the prepared PiRealy software. The set also includes a housing that allows you to mount the module on a DIN rail.
