WP8024ADAM - IO module with RS485 interface

Module with eight 240V/2A relays controlled by 5V with a fuse triggered by a low state. modSSR-8CH-L

This industrial relay module, powered by the Raspberry Pi RP2350B microcontroller, features six 10A 250VAC/30VDC relays and an isolated RS485 interface. It ensures safe and stable operation thanks to opto-isolation, power isolation, and surge protection. It supports programming in C/C++, MicroPython, and the Arduino IDE, and the 40-pin Pico HAT connector allows for easy expansion. Its robust DIN housing and 7–36V DC power supply make it ideal for industrial automation and IoT projects. Waveshare RP2350-Relay-6CH

4-channel switch module with a maximum voltage of 16 V and a current of 2 A based on a MOSFET transistor. It is controlled by digital inputs. It is equipped with a screw connection and status LEDs. Adafruit 5757

Industrial relay module controlled via RS485 interface with Modbus RTU protocol support, offering 8 outputs with maximum load of 10 A. Equipped with galvanic isolation, opto-isolation, TVS diodes and DIN mounting, it ensures safe and reliable operation in harsh industrial conditions. Thanks to functions such as flash-on/off, configurable RS485 address (1-255), signaling diodes and wide power supply range (7-36 V), the module is perfect for building automation and device control.
