AS-Interface Switch Cabinet Module KE5 – Simple Handling and Improved Manageability

AS-Interface switch cabinet module KE5
Where conventional AS-Interface modules fall short, the KE5 succeeds with a unique housing design that saves space and enables maximum management

The strengths of AS-Interface technology are well known throughout factory automation. In addition to the low installation costs and flexible expandability, users appreciate the simple assembly and easy configuration of AS-Interface systems.

One of the few remaining challenges is the setup of larger amounts of I/O inside switch cabinets and junction boxes. Trying to manage and organize your wiring within a limited installation space is a real headache.

Pepperl+Fuchs' KE5 switch cabinet module is the newest member of our AS-Interface cabinet module family. A unique housing design enables distinct visibility and simplifies mounting, wiring, and maintenance inside switch cabinets and junction boxes. 

Front side push-in connection for easy mounting

During commissioning, terminal blocks are plugged in seperately from one another

Almost all AS-Interface modules feature spring and screw terminals that are positioned on the top and bottom of the module. The KE5 takes a different approach: connection points are located on the front and are simply pushed into the module.

The push-in connection at the front and individual plug-in terminals make installation quicker and easier. Cables are plugged-in in no time, and conveniently guided downward towards a single cable duct


Designed for savings

The KE5 significantly simplifies mounting and removal of the connectors, brings organization to the switch cabinet, and opens up additional installation space. With connection at the front of the device, modules can be mounted flush on the upper edge of the switch box or cabinet. Together with the narrow KE5 housing, <19 mm, you can achieve up to 50% space savings.

A simple design brings many benefits

Relay and electronic output versions of the KE5 have the same housing, bringing a cleaner look and making it easy to mount and determine cabinet space requirements

The hinged, half-transparent front cover  was ingeniously designed to maintain at-a-glance I/O status even when open, provide a label for unmistakable I/O association, and cleverly route the cables so they can be bundled for a clean and organized cabinet. 

For diagnostic and maintenance tasks, the KE5 features an intelligent display with backlit I/O identification and status-indication LEDs. It provides distinct I/O association, even in dark environments. Dual color LEDs are used to indicate overload of an output on a channel-specific basis. 


Terminal bridging and selectable sensor supply

In addition to the innovative housing and cover design, the KE5 comes with advantages on the inside. The terminal contacts for AS-i and AUX, which are internally bridged, achieve the full 10 A, eliminating the cumbersome double-wire-end ferrules at  terminal points. 

With an easily accessible switch, you can opt for sensor supply internally from AS-i or externally through AUX -- with a functional safe separation of both supply methods. This reduces the range of devices required, saves on costs, and increases plant availability. 

The AS-Interface KE5 switch cabinet module is the right choice for AS-Interface users who want easy handling, flexible technology, and cost efficiency.
