BECKHOFF EL9520 EtherCAT Terminal AS-Interface Potential Feed Terminal with Filter

Description

Designed for seamless integration into the EtherCAT Terminal system, the BECKHOFF EL9520 potential feed terminal supplies and filters the power transmission within AS-Interface network segments. It features an integrated data decoupling filter that isolates the DC power supply from the data transmission, allowing a single standard power supply to drive the network without signal corruption. The terminal operates passively within the system, requiring no network addressing or specialized software configuration, which simplifies commissioning and deployment. With a compact 12 mm width and status LED indicators, the module optimizes control cabinet space while providing clear diagnostic visibility.

Features

• Integrated decoupling filter for reliable AS-Interface network data and power isolation.
• Supports continuous current loads up to 2 A.
• Electrical isolation of 500 V between the E-bus and the field potential.
• Passive operation requiring no address assignment or configuration parameters.
• Compact, space-saving 12 mm terminal housing.

Applications

• Industrial fieldbus networks utilizing AS-Interface.
• Power conditioning and distribution in manufacturing automation.
• Control cabinet assembly in water treatment, packaging, and materials handling industries.
