The Pepperl + Fuchs VAA-4E4A-KE-ZEJQ/E2L is a sophisticated AS-Interface sensor/actuator module designed for seamless integration into control cabinet setups. This compact unit, with dimensions of 106 x 102 x 22.5 mm, is engineered to occupy minimal space while delivering robust performance. It is easily mounted onto a standard DIN rail, adhering to EN 50022 specifications, which ensures a secure and straightforward installation process.
Equipped with four inputs and four electronic outputs, this module is capable of interfacing with both 2- and 3-wire sensors, providing flexibility for a variety of industrial applications. The inputs and outputs are connected via mechanically coded, colour-coded, removable terminals, which prevent incorrect wiring and facilitate maintenance.
The module offers a dual supply option for sensors, allowing users to choose between internal supply from the AS-Interface or an external voltage source. This feature is complemented by an intuitive side switch for easy selection and an LED indicator for the internal supply status.
For operational reliability, the VAA-4E4A-KE-ZEJQ/E2L includes a communication monitoring function that deactivates outputs if the AS-Interface fails to communicate with the module for an extended period. This safety feature can be toggled via parameter settings, along with input pulse suppression and lead breakage detection for the outputs, enhancing the module's diagnostic capabilities.
The module's LED indicators provide real-time feedback on the bus, external auxiliary voltage, sensor supply, and the status of inputs and outputs. In the event of an output overload, a dedicated red LED per channel alerts the user to the issue.
Designed for indoor use, the module operates within an ambient temperature range of -25 to 60°C and is rated with a degree of protection of IP20, ensuring it is safeguarded against solid objects larger than 12.5 mm but not against water ingress.
Overall, the Pepperl + Fuchs VAA-4E4A-KE-ZEJQ/E2L module is a reliable and versatile component for industrial automation systems, offering precise control and monitoring of sensors and actuators within a compact and user-friendly design.
