Modular Remote I/O

Modular I/O blocks, communicating through Modbus, Profibus, Can Open and Ethernet, can exchange up to 64 I/O per unit when the processor is integrated and programmable.

  • Filtering and counting on digital inputs.

  • Threshold or scaling on analog inputs.

  • Time delays on digital outputs.

  • Freezing or fallback of digital and analog outputs in the event of a fault.

Installation and maintenance of I/O applications are facilitated by the accessibility of the electronic parts and large labeling areas. This avoids the need to touch the wiring after installation. The connector blocks have from 1-4 adjacent rows and avoid the need for intermediate terminal blocks, resulting in significant time and equipment savings.

Functions directly integrated in the I/O modules lighten the load of the automation control system, by enabling counting operations, time delays on the digital I/O, or the processing of alarm thresholds on the analog inputs while retaining direct access to the images of the physical I/O via the fieldbus.

More sophisticated functions (sensor/actuator type processing algorithms or remote PLC) enable the MIDU to fully support distributed intelligence in your application.

Inductive and Capacitive Proximity Sensors

Crouzet offers an extensive range of inductive and capacitive proximity sensors, with more than 350 references and covering almost the entire range of detection needs for industrial machinery.  You benefit from competitive pricing, with particular plastic connector versions at the same price as versions with cables.  Rapid delivery is guaranteed for a large number of components.

In the cylindrical versions, different models are offered to respond to numerous conditions of use: long or short housing, plastic housing, stainless steel housing, etc.  The latter provide a solution to specific needs in the food processing industry.

A complete NAMUR DC 2-wire range (DIN standard 19234) in plastic or stainless steel comes in 4 models M8, M12, M18, and M30.  The range is also complemented by rectangular models designed for conveyor applications, with the flat pack version, and a 40x40 rotating head version.  A new offer of capacitive sensors is also available with M30 cylindrical and flat pack versions which have very high immunity to electromagnetic interference.

The new Crouzet IPDs are also perfectly suited to their operating environments: workshops, industrial machines, control systems, etc.  There is a choice of plastic or metal connectors for most products.

Photo-Electric Detectors

These are used to detect the presence or absence of an object by reflecting or blocking a beam of light.  The Crouzet range combines concern for essential features such as the sensing range, precision, size and accessibility, with ease of installation.
