Modular I/O solution for mixed IP20 and IP67 applications

In addition to centralised automation technology, there is also an increasing need for decentralised, intelligent control systems to bring greater flexibility to production environments.AIC Technik has responded to this need with u-mation, a modular hardware portfolio which can be flexibly combined and extended and which applies equally to a traditional panel application as well as a decentralised controller.

Part of this this portfolio includes u-remote, a remote I/O concept consisting of a range of modules that allow users to connect signal systems in the panel, in mixed IP20 and IP67 applications or directly in the field. Benefits are said to include speeding up of the installation process.

Where systems grow to a size where the count of signals is too great for the cabinet, the UR67 provides an I/O and fieldbus solution for the collection of local signals. It encapsulates signals with IP67 protection at the very point where sensors and actuators are located. It supports common fieldbus systems, while incorporating multi-protocol variants for those wishing to standardise on an I/O block.

UR67 is said to offer a solution where production environments require a high number of sensors and actuators in the field need to be connected to a central control system.

The UR20 multi-protocol distributed remote I/O allows users to keep their remote I/O station as compact as possible. The header module also provides individual current paths for inputs and outputs, resulting in fewer additional power feed modules for larger systems to keep systems compact while providing flexibility for expansion.

Suited for use in applications in decentralised control systems, where they can reduce the amount of field wiring needed, the new modules are designed for use with conventional sensors and low-power actuators. As an added benefit, the input modules feature integrated user-configurable filters which, in many cases, further simplify control system design.

The range includes modules with either six or ten M12 ports, with each port capable of supporting two digital inputs or outputs. Additionally, all modules are offered in coolant-resistant versions, which are colour-coded orange and are suitable for general industrial applications. Hygienic versions, which are colour coded grey, are intended for use in food manufacturing and similar applications.Input modules in the AL2xxx range offer pre-processing of input signals before they are passed to the IO-Link system using filters that include debouncing, stretching and inverting. By using these filters, signals with a minimum duration of 1.5msec can be reliably detected. Output modules can be fed from two independent electrically isolated voltage sources, with half of the ports powered from each source.

Coolant-resistant AL2xxx IO-Link extension modules have an IP67 ingress protection rating, while hygienic versions are rated IP68/IP69K. Available accessories include pre-terminated connecting cables, IO-Link masters with fieldbus interfaces, and a USB IO-Link master for parameter setting and fault diagnosis.
