Pepperl+Fuchs VAA-4E4A-KE1-Z/E2 186880

The AS-Interface Module VAA-4E4A-KE1-Z/E2 is a control cabinet with 4 inputs and 4 electronic outputs. The housing, only 22.5 mm in width and 48.5 mm in height, takes up little place in the switch cabinet. The module features an integrated addressing jack is mounted by snapping onto the 35 mm DIN rail in accordance with EN 50022. For easy disconnection for commissioning and servicing, the connection is via plug-in black 4-pin spring terminals. The external auxiliary voltage, the AS-Interface cable, the inputs and outputs (IN and O), as well as the plus potential of the inputs (I+) and the minus potential of the outputs (O-) are connected with the module via double terminals. The inputs and outputs and the connected sensors and actuators are supplied via external auxiliary power UAUX. Polarity reversal is signalled by a red light on the AUX-LED. The current switching status is indicated for each input and output by means of an LED on the top of the module. Note: The device features communication monitoring. It switches off the power to the outputs when no communication has occurred on the AS-Interface cable for more than 40 ms. In the event of overloading of the outputs, e.g. due to short-circuiting, the FAULT-LED on the module flashes and a signal is communicated to the AS-Interface master via the Peripheral error function. Communication via the AS-Interface remains uninterrupted.
