AS-Interface – speeding up installation
28 April 2015
Pepperl+Fuchs has introduced a new range of AS-Interface IP20 modules which feature a push-in front connector.
The easily accessible push-in connection at the front of the device allows crimped wire ends to be inserted directly into the push-in terminals, helping to speed up the installation process.
The entire wiring harness is guided downward, meaning there is no need for the upper cable ridge/cable duct. This provides a solution for the switch cabinet wiring, offers space savings and ensures clarity.
In switch boxes, modules featuring this connection can be mounted flush on the upper edge of a switch box, without impairing installation. A transparent hinged cover, which can be snapped into place at multiple points, offers a clear view through to the digit display at all times and enables the terminal functions to be colour-coded internally. The terminals can be removed individually and are coded to prevent them from being mixed up, meaning devices can be replaced without any problems.
The IOs are displayed and diagnostics are performed centrally by means of backlit numbers. There is no need to assign labels to LEDs. This setup also ensures that information can be read even in dark conditions. Dual LEDs are used to indicate overload of an output on a channel-specific basis.
