Tinycontrol tHAT2 Expansion Board with 4x Relay and MODBUS for LAN Controller LK3

The board allows for easy addition of 4 relay outputs with open collector directly controlled from the PWM outputs of the LAN Controller, which increases flexibility and automation options. The provided outputs OUT1–OUT4 along with 3.3 V power for sensors and analog inputs INPA1 and INPA2 offer convenient connection of sensors and peripherals without complex wiring.

The built-in RS485 converter for Modbus enables stable and reliable communication in both industrial and home automation networks. The board is also available in a version with IDC10 connectors for connecting relay modules, simplifying installation and speeding up deployment into existing systems. An ideal solution for professional expansion of controllers HW 3.7 and 3.8.
