Introducing Linortek Ethernet I/O Controller

The Linortek Ethernet I/O controller is built on standard TCP/IP platform with a built-in web server that you can access, control and monitor your equipment over the network from any standard web browser, no add-on software to install, no programming skills are required.

Using Linortek industrial Ethernet IO controller`s relay switched outputs, opto-isolated digital inputs and analog inputs, you can upgrade any stand-alone physical hardwired equipment to a network enabled product for remote control and data acquisition. The built-in MQTT protocol provides a standard method of communication with any IoT platform and application and integrates acquired data into your own system.

Local & Remote Control & Monitoring

The Linortek industrial Ethernet I/O controller is NOT a cloud-based system. All data is stored locally at your facility giving you full control of collected records. To use the controller locally, connect it to your local network using TCP/IP communication over Ethernet with the provided RJ45 cable. If needed, data transfer can be done through RESTful API, XML and MQTT.

The Linortek Ethernet IO controller can also be used for remote control & monitoring by port forwarding the device to the Internet to obtain a web address – now you can access, control and monitor your equipment at anytime from anywhere with an Internet enabled device. Using the MQTT protocol, the controller can publish collected data as MQTT message to a broker. Subscribe your system/application to the same broker and topic to view the data from your own system, making the Linortek device a great tool for your Industrial Internet of Things applications.

Ethernet IO Controller Peer to Peer Communication

Peer-to-Peer Communication (P2P)

Each Linortek Ethernet I/O controller is an independent system that includes the hardware and software for installation and data acquisition. Once connected to the network, Lonortek controllers can “talk” to each other over the network (peer-to-peer (P2P) communication system), this allows you to use one device to control the others remotely, eliminating the need for running long wires and for having central station. The P2P communication function is simple to use: just link the IP addresses together from the Remote Devices setup page, enter the IP address, login credentials, setup the condition logic task, you are all set.

Condition Logic Control

Using the condition-logic task builder, you can easily create tasks based on inputs or outputs’ status using IF…THEN… THAT statement. Create up to three actions for each task providing you with the ultimate control and monitoring solution for your project.

Advanced Features

Linortek ethernet io controller RESTful API


RESTful API is an interface that two computer systems use to exchange information securely over the Internet. Most business applications have to communicate with other internal and third-party applications to perform various tasks. With the RESTful API, you can easily control the device or pull the data from the I/O controller without the need of logging onto the device, or integrate the data to a 3rd party system.


MQTT is a simple messaging protocol, designed for constrained devices with low-bandwidth, it’s the perfect solution for Internet of Things applications. MQTT allows you to send commands to control outputs, read and publish data from sensor nodes and much more. MQTT is added to our latest development – Ultra 300 controller and iTrixx WiFi hour meter, for more efficient and secure data communication. The new development provides a standard method of communication for Ultra 300 to reliably communicate data across networks with any IoT platform and applications, it simplifies communication between Ultra300 and other devices, enabling Ultra 300 to become a standard product in IIoT arena for data acquisition.

The Hardware & Software

We have worked with many customers using the Linortek Ethernet I/O controller to create various customized applications to meet their unique requirements. With the relay outputs, digital inputs and analog inputs built on the board, other sensors and devices can be connected to the I/O controllers to monitor a range of data, such as temperature, humidity, oil pressure, light levels, impact, voltage, RPM and more.

Relay Output

Each Linortek Ethernet I/O controller is equipped with various web relays that can be turned on, off, or pulsed using a web browser. Using the built-in web page and condition-logic Task Builder, you can use the relays to automatically control countless sorts of equipment, including pumps, motors, lights, gates – almost any powered device, whether they it`s in the same network, or different networks, or even in remote locations.

Analog Input

The analog inputs allow the Server to read the value of external equipment. They are non-isolated, use provided power for eliminating ground loops, provide 5VDC@30mA 3.3VDC power source, PTC protected. Fargo R4ADI has two analog inputs that are specifically designed for interfacing with current sensors, allowing current monitoring of external equipment.

Digital Input

The digital inputs allow the Ethernet I/O controller to detect an external on/off state of a sensor. With this information the SERVER can display whether an input is on or off, count events in a resettable or non-resettable counter, and calculate the frequency (such as for use as a tachometer) or the period of the input.

Web Page

The Linortek Ethernet I/O controller is DHCP enabled, when the controller is first installed on your network, it automatically obtains an IP from your router via DHCP if your router is set up to assign one. With the IP address, you can access the built-in webpage for initial setup and create your advanced tasks.
