Tinycontrol LAN Controller v3.9

LK3.9 is continuation of v3.5 series. It has same API. Is recommended for typical monitoring and automatization applications in IT enviroment. This version is equipped with a faster processor ARM 32F407. It has the same functions but different firmware series since v3.5.
The device features a built-in web server (similar to all LK versions) for viewing readings and configuring settings via a web browser.

Key Features:

  • 2 analog inputs with switchable gain (measuring from 1 mV to 33 V): suitable for measuring voltage, DC current, AC current (with additional sensors), pressure sensors, thermocouples, distance sensors, photoresistors for light measurement, and many more.
  • 2 analog inputs with switchable gain (measuring from 1 mV to 55 V): for measuring voltage, DC current, AC current (with additional sensors), pressure sensors, thermocouples, distance sensors, photoresistors for light measurement, and others.
  • 2 analog inputs for measurements up to 3.3 V: for voltage and current measurements (DC and AC via additional sensors) and 4-20mA converters.
  • I2C bus for connecting sensors via RJ12 connector: supports a wide range of I2C sensors (list below) and DS18B20 via the 1-Wire bus.
  • Serial bus (UART).
  • Bus for RS485 converter - MODBUS RTU (additional board required): allows reading pre-configured devices and setting up configurations to read any device using the Modbus protocol.
  • 4 logic inputs: as status sensors for door monitoring, infrared motion sensors, buttons for manual switching with a bistable mode option, pulse counters for energy meters, and timers for input resets.
  • 1 relay (NO, C, NC).
  • 1 transistor output: power supply voltage output, for controlling loads with up to 0.5A current consumption.
  • 4 outputs for relay/transistor switching in OC standard.
  • 4 PWM outputs from 50 Hz to 100 kHz.
  • Measurement of supply voltage and on-board temperature.
  • Ethernet communication (10/100Mb) with 802.3af PoE support.
  • Management via a web interface.
