Proven Ethernet I/O Controllers
Transform stand-alone equipment into smart, network-enabled systems with our reliable TCP/IP web-based controllers. Control relays, monitor inputs, and automate tasks—all with built-in web servers and no monthly fees.
Fargo and Koda are Linortek’s proven TCP/IP web-enabled I/O controllers with built-in web servers, designed for remote control and monitoring of industrial equipment, building automation, security systems, and more. Built on a reliable TCP/IP platform, these controllers allow you to access, control, and monitor your equipment over the network or via the Internet from anywhere with any web browser.
No add-on software is needed to install, no special programming skills are required. Using relay switched outputs, digital inputs, and analog inputs (on select models), you can upgrade any stand-alone physical hardwired equipment to a network/Internet enabled product for remote control and data acquisition.
With Fargo and Koda, you get the software built-in, no need to install any additional software. No fees! These are one-time purchases with no recurring subscription costs or cloud dependencies.

Hardware & software for installation and operation included, no software to purchase, no 3rd party server
POE enabled (select models), DIN rail or panel mount options, terminal block connectors for quick, hassle-free installation.
Browser-based setup, logical condition/action for I/O with no scripting required
Controllers work on your local intranet—data doesn't go above the firewall. Your data stays secure on your network under your control.
Collected data can be integrated to a 3rd party software/system using XML, JSON, RESTful API
One-time purchase with no recurring subscription costs or cloud fees
Both Fargo and Koda controllers are built on the same reliable platform. Choose based on your form factor needs and I/O requirements.
Bare board units with up to 8 low voltage relay outputs, 4 optically isolated digital inputs, and 4 analog inputs. Perfect for custom installations and OEM applications.
Housed units with DIN rail mountable enclosures that can be snapped onto DIN rail or attached to any flat surface. Includes built-in sensors for comprehensive monitoring.
Web controlled relay board with real-time remote control capability and email alerts. Securely control up to 8 different devices simultaneously over the Internet using any standard browser.
Ethernet I/O controller with 4 relay outputs and 4 digital inputs. Digital input data can be used to calculate a range of results such as state, counter, frequency, and period. POE enabled for easy installation.
Full-featured TCP/IP web-enabled relay control & monitoring I/O board with 4 relay outputs, 4 digital inputs, and 4 analog value inputs. Two analog inputs are specifically designed for current sensors to monitor external equipment. POE enabled.
Web-enabled, TCP/IP Ethernet relay controller in a DIN rail mountable enclosure. Ideal for remote monitoring & control systems with 2 relay outputs and 2 digital inputs. Can be snapped onto DIN rail or attached to walls or under counters.
Web-enabled, TCP/IP Ethernet relay controller in a DIN rail mountable enclosure. Ideal for remote monitoring & control systems with 4 relay outputs, 2 digital inputs, and 1 temperature/humidity sensor input.
Both Fargo and Koda controllers share the same robust platform features that make automation simple and reliable.
Access, control, and monitor your equipment from anywhere using any web browser. No special software installation required.
Use locally on your network for secure control, or enable remote access via port forwarding to monitor and control from anywhere in the world via the Internet.
Devices can communicate with each other over the network without a centralized system. Build distributed control systems where one device controls others using simple IP linking.
Create automation tasks using IF…THEN…THAT statements based on input or output status. Set up to three actions per task without any programming knowledge.
Control devices and pull data without logging in. Integrate with third-party systems and applications for seamless automation workflows.
Whether you need to remotely reboot equipment to save a service call, control a timed alert system for schools or factories, monitor temperature and humidity in server rooms or commercial freezers, or collect runtime data for preventative maintenance across hundreds of pieces of equipment—Fargo and Koda can do the job reliably and affordably.
