Transform Your Industrial Equipment to Be a Network-Enabled System for Remote Control and Data Acquisition
Linortek’s Ethernet I/O controllers are built on a TCP/IP platform with a built-in web server, using relay outputs, digital inputs, and analog inputs, you can upgrade any standalone devices into network-enabled systems for remote control and data acquisition. With MQTT protocol and RESTful API, you can seamlessly integrate data into IoT platforms or your existing systems with no monthly fees.

Our web-enabled controllers deliver the reliability, security, and flexibility required by modern industrial environments.
Connect seamlessly with existing software platforms via MQTT, XML, JSON, or Restful API.
The eIO controllers are NOT a cloud-based system - all data is stored locally at your facility giving you full control of collected records.
Eliminate recurring cloud service fees and expensive specialized software with our built-in web server and intuitive interface.
Monitor and control your equipment from anywhere using a standard web browser, with instant alerts and status updates.
Create automation tasks with conditional logic directly on the device.
Use for smart irrigation, gate control, building lockdowns, and more.
The eIO controller combines powerful capabilities with user-friendly design to transform how you manage your industrial automation.
Built-in web server, no additional software or designated computer required.
Seamlessly integrate with industrial IoT platforms using the industry-standard MQTT protocol, enabling efficient device-to-device communication and data exchange.
Equipped with relay outputs, digital inputs, and analog inputs to handle a wide range of industrial control requirements and sensor data acquisition.
See why our solution stands out from traditional PLCs and cloud-based controllers.

Each eIO 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.
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.
The digital inputs allow the eIO 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.
The eIO 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.
RESTful API is an interface that two computer systems use to exchange information securely over the Internet. With the RESTful API, you can easily control the device or pull the data from the eIO 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 enables Linortek eIO controllers to send commands and data to each other efficiently, secure communication across IoT (Internet of Things) networks, improve the communication capabilities and make them more compatible with industrial IoT systems.
Don’t just take our word for it – hear from the engineers and facility managers who rely on our controllers every day.



The Linortek Ethernet I/O controller is built-on standard TCP/IP product platform with a built-in server, relay outputs, digital inputs and analog inputs, making the this device a great fit for literally thousands of applications. Whether you are looking for a simple device to remotely reboot your equipment to save a trip, remotely control a timed alert system, monitor temperature & humidity for a cooler, commercial freezer, server room, or a solution to collect runtime data for preventative maintenance for hundreds of equipment – Linortek has the solutions.
Linortek products offer several key advantages:
– Industry-leading reliability through comprehensive pre-shipping testing and quality control
– Expert in-house technical support with direct access to engineers
– Streamlined installation process with plug-and-play functionality
– Full system integration capabilities with existing building management systems
– Made in USA with industrial-grade components for maximum durability
– Competitive pricing through direct-to-customer sales model
– Customization options to meet specific facility requirements
– Regular firmware updates and feature enhancements at no additional cost
While both devices share the same hardware platform, they serve different purposes:
Netbell-2:
– Pre-installed with specialized bell scheduling software
– Designed specifically for automated bell system control
– Complete bell management solution
Koda 100:
– General-purpose web relay control board
– Flexible platform for various control applications
– No pre-installed scheduling software
The only function for the battery onboard is to power the board’s internal clock. All settings and programs are safely stored in permanent memory, so no data will be lost if the battery drains. When the controller is powered back on, a fully depleted battery will recharge automatically within 5 hours.
All data is stored locally on your Linortek device through its built-in server. Your schedules and settings remain securely on the device itself, not in the cloud.
Get enterprise-grade control at an affordable price – with no recurring costs or specialized programming required.
