Details: VAA-4E4A-KE2-DK


The data coupler module VAA-4E4A-KE2-DK is used to exchange data via two AS-Interface circuits. The data coupler itself consists of two 4E4A slaves in a single housing. The output bits of the AS-Interface circuit 1 are represented at the AS-Interface circuit 2 as input bits, and vice versa. This permits a bidirectional data exchange without the need to transfer the data via an overriding control. This is a particular advantage in time-critical applications. The addressing of both integrated AS-Interface slaves is mutually independent. Two addressing jacks are available on the front panel.

By using two independent AS-Interface connections the related inputs and outputs are electrically separated. This prevents problems with potential shifting (mass potential).

For status indication each slave has 6 LEDs on the front panel, 4 LEDs for the 4 outputs, 1 LED for the voltage indication, and 1 LED for indicating AS-Interface error messages.

The housing of only 22.5 mm width requires little room in the switch cabinet. The module is installed by snapping it onto the 35 mm mounting rail in accordance with EN 50022.

Connections are made via pluggable screw terminals. This enables the easy disconnection during commissioning or service.
