Turck’s Compact FEN20 I/O Block Simplifies Configuration and Monitoring via IO-Link

The compact block offers four IO-Link channels. It is ideal for a wide range of industries, including manufacturing where space is at a premium, on robot end-effectors where small I/O is needed, and in automotive manufacturing and Tier 1 plants.

MINNEAPOLIS, MN (April 23, 2019) - Turck introduces the FEN20-4IOL industrial Ethernet I/O module, which uses IO-Link to improve device configuration, monitoring and replacement in industrial applications.


The compact block offers four IO-Link channels. It is ideal for a wide range of industries, including manufacturing where space is at a premium, on robot end-effectors where small I/O is needed, and in automotive manufacturing and Tier 1 plants. In addition to the device functioning as an IO-Link master, each of the IO-Link (C/Q) pins can optionally be configured as digital input or output.

The FEN20-4IOL is also a Field Logic Controller (FLC). As an FLC, the module can carry out control tasks at the field level. This enables users to implement simpler applications without the need for an additional PLC. In more complex applications, the FLC function provides the processing requirement for the parent control system. Configuration and programming are carried out via Turck's ARGEE web-based engineering system.

With multiprotocol plug-and-play functionality, the FEN20 devices are immediately ready for use in PROFINET®, Modbus® TCP or EtherNet/IP™ systems. The device detects the protocol used by listening to the communication traffic during the startup phase. The FEN20 device measures just 55x62.5x30 mm and carries an IP20 rating, and fits in small control boxes, control panels or other existing housings.

The FEN20-4IOL is equipped with an integrated EtherNet switch and a built-in web server to display diagnostic information and provide access to device configuration parameters. The web page was created with a responsive design so that even a smartphone can be used for simple diagnostics.

How Cabinet Coolers Can End Costly Shutdowns

A low cost, reliable way to cool and purge electronic control panels. EXAIR Cabinet Coolers incorporate a vortex tube to produce cold air from compressed air - with no moving parts. NEMA 12, 4, and 4X Cabinet Coolers that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels. Cabinet Coolers convert an ordinary supply of compressed air into clean, cold 20ºF air.
