Your Project, Your Rules – Connectivity Without Limits with 4G
The tinycontrol LK4 4G frees your automation ideas from the shackles of infrastructure. Thanks to the integrated 4G modem, you only need a mobile signal to monitor and control your system worldwide. Whether for temperature monitoring in a remote holiday home, controlling an irrigation system in the field, or monitoring technical installations in containers – the LK4 4G ensures a stable connection. Additionally, the Ethernet port and the Wi-Fi module, which can operate as both a client and a WiFi Access Point, offer maximum redundancy and flexibility. You can even use both interfaces simultaneously to build a fail-safe Network.
One Controller for All Cases: Connect Sensors and Actuators Effortlessly
The true strength of the LK4 4G lies in its incredible versatility. Forget complicated gateways or add-on modules. This IoT Controller offers you a huge range of interfaces directly out of the box. Connect up to eight DS18B20 temperature sensors to the 1-Wire bus, integrate modern I2C sensors for humidity, pressure, or CO2, or read your energy meters via the pulse counting inputs or the Modbus RTU interface. With a powerful relay, multiple transistor and PWM outputs, and analog inputs, you can precisely switch and measure what is important for your project. It becomes the central intelligence in your entire Network.
On-Board Intelligence: Self-Sufficient Control with Events and Scheduler
Why be dependent on a cloud when intelligence can be right on site? The LK4 4G features highly developed software that allows you to create complex automation rules directly on the device. With the 'Events' function, you can define actions triggered based on up to three sensor conditions with logical operators – for example, 'If temperature > 25°C AND window contact open, THEN send SMS'. The integrated scheduler also enables up to 50 time-controlled actions. This self-sufficient control logic ensures maximum reliability, as it continues to function even if the internet connection is interrupted.
Professionally Powered and Mounted: PoE and DIN Rail
Designed for professional use, the LK4 4G also excels in the basics. The wide input voltage range of 8 to 58 Volts DC makes it compatible with most power supplies. The smartest option, however, is Power Supply via Power over Ethernet (PoE 802.3af). This means you only need a single Network cable for data and power, which significantly simplifies installation. You can, of course, find suitable PoE Injectors / Power Supplies with us. Thanks to the housing suitable for DIN rail (35mm), the IoT Controller can be mounted neatly and securely in any standard control cabinet.
