Pepperl + Fuchs VAA-4E4A-KE5-ZEJQ/E2L

The Pepperl + Fuchs VAA-4E4A-KE5-ZEJQ/E2L is a compact and efficient AS-Interface sensor/actuator module designed for seamless integration into switch cabinets. With a slender 19 mm housing width, this module is an ideal solution for space-constrained environments, easily mounting onto a standard 35 mm DIN rail in accordance with EN 50022.

This module boasts four inputs and four electronic outputs, facilitating a robust connection for a variety of industrial sensors and actuators. The push-in connection technology, complemented by mechanically coded terminal blocks, ensures a secure and straightforward installation process. Users have the flexibility to select between internal module supply or an external voltage source for sensor supply, thanks to a conveniently placed switch on the module's side.

Operational status and diagnostics are made simple with the module's intuitive function display. This includes indicators for bus status, external auxiliary voltage, internal sensor supply, inputs, and outputs. Additionally, each output channel is equipped with a red LED that illuminates in the event of an overload, providing immediate visual feedback for troubleshooting.

The VAA-4E4A-KE5-ZEJQ/E2L module is designed with safety in mind, offering safe galvanic isolation between the output part supplied by AUX and the rest of the circuit components. This feature enables the module to be used in applications that demand reliable power supply switch-off for emergency stop functions, adhering to safety classification PLd.

With a focus on reliability, the module includes a communication monitor that deactivates the outputs if the AS-Interface fails to communicate with the module for more than 40 ms. This safeguard, along with the ability to activate input filters and lead breakage detection via programmable parameters, ensures consistent and safe operation.

Constructed with high-quality materials, the module's housing is made from PA 66-FR, and it has a mass of 110 g. The module's technical specifications align with industry standards, including compliance with electromagnetic compatibility and machinery directives, ensuring broad compatibility and adherence to regulatory requirements.

The Pepperl + Fuchs VAA-4E4A-KE5-ZEJQ/E2L is a testament to intelligent design and engineering, offering a reliable and user-friendly solution for industrial automation needs.
