Product Description

​The Pepperl+Fuchs VAA-4E4A-KE-ZEJQ/E2L is an AS-Interface (AS-i) sensor/actuator module designed to facilitate the connection and communication of sensors and actuators within an AS-i network. It features four inputs compatible with 2-wire and 3-wire PNP sensors, as well as four electronic outputs capable of driving up to 2 A per channel. The module offers flexibility in sensor power supply, allowing selection between internal or external sources. Diagnostic features include communication monitoring and individual LED indicators for each input and output, providing clear status information and aiding in troubleshooting. The housing is equipped with removable, color-coded terminals for straightforward wiring and maintenance.
