Tinycontrol LAN controller, v3.9

The advanced LK3.9 module offers the ideal solution for monitoring and automation in IT environments. With a fast ARM 32F407 processor and a compatible API from the v3.5 series, it provides reliable performance for all standard applications. The built-in web server allows for device management and configuration via a web browser, clear visualization of measurements, and quick parameter settings. The module features 2 analog inputs with a switchable range of 1 mV–33 V and 2 inputs 1 mV–55 V for voltage, current, pressure sensors, thermocouples, photoresistors, and distance sensors, as well as 2 analog inputs up to 3.3 V for 4–20 mA current converters.

Key features via web interface

• Display of data from sensors with customizable user and administrator panels
• Configuration of events and scheduling of actions
• Setting up the OLED display
• Configuration of MQTT client, HTTP client, and SNMP protocol
• Setting up email notifications
• Access management and firmware updates
• Configuration of local or network time (NTP)

Flexible communication and output control

The device offers I2C and 1-Wire bus for a wide range of sensors, along with serial UART and RS485 bus supporting Modbus RTU for integration into existing systems. It is also equipped with 1 relay, 1 transistor output, 4 OC outputs, and 4 PWM outputs for switching and regulating loads. The module monitors power voltage and temperature directly on the board and allows for Ethernet communication with PoE support, ensuring reliable and flexible infrastructure control directly through the web interface.
