The Pepperl + Fuchs VAA-4EA-KF-ZE/R is a high-performance interface sensor module that forms part of the VAA series, designed to facilitate seamless integration into AS-Interface systems. This module is equipped with four inputs (PNP) and four relay outputs, making it a versatile solution for a wide range of industrial automation applications.
Crafted with precision, the module boasts a compact housing that includes removable, coded terminals for straightforward installation and maintenance. The unit's slim 40 mm profile ensures it occupies minimal space within a control cabinet, allowing for efficient use of space.
The VAA-4EA-KF-ZE/R operates within a voltage range of 26.5 to 31.6 V and maintains an operating current of ≤110 mA. It features a robust design that can handle relay output loads up to 8 A per module, providing reliable performance even in demanding environments.
For ease of use, the module includes a Power Rail connection for AS-Interface communication and a dedicated addressing jack for device configuration. The module's functionality is further enhanced by its communication monitoring capabilities, which ensure safety by turning off outputs in the event of a communication interruption.
The interface sensor module is also equipped with LED indicators for bus, inputs, and outputs, offering at-a-glance diagnostic information to users. These indicators help in quick troubleshooting and monitoring of the system's operational status.
Designed to meet the requirements of modern industrial settings, the Pepperl + Fuchs VAA-4EA-KF-ZE/R module is a reliable and efficient choice for those seeking to optimise their automation systems with high-quality interface sensors.
