Product description: IoTPi - 4-channel RS485 relay module RP2040 + ESP8266 WiFi - SB Components SKU24162
The IoTPi module is equipped with 4 relays with galvanic separation and is based on the Raspberry Pi 2040 microcontroller with the ESP8266 module. The additional ESP system allows for WiFi communication, so you can create a simple system that allows you to remotely turn on and off devices or lighting. The maximum load of the relays is 10 A for 230 V AC and 30 V DC . The EL357NC optocoupler enables safe regulation of high voltages or currents. IoTPi with four relays is equipped with an AC / DC converter, thanks to which it can be connected directly to the 230 V AC power supply. The module can also be controlled using the prepared PiRealy software. The set also includes a DIN rail housing.
