PFEA113-20 | 3BSE050092R20 | Fieldbus Power Supply Module

Description

Technical Specifications

Key Features and Advantages

The **PFEA113-20** provides galvanically isolated power distribution for fieldbus networks, ensuring signal integrity in electrically noisy environments. Its dual-stage filtering eliminates high-frequency interference while maintaining <50mV ripple on output lines. The module supports hot-swapping without network interruption, critical for continuous process operations. LED indicators for power status and network activity enable quick diagnostics.

Compact DIN-rail design allows high-density installations in control cabinets. Built-in short-circuit and overload protection (5ms response time) safeguards connected devices. Pre-configured termination resistors simplify PROFIBUS network setup, while the wide operating temperature range ensures reliability in foundries and cold storage facilities.

Application Areas

In automotive manufacturing, the **PFEA113-20** powers sensor networks on robotic welding lines. Chemical plants utilize its isolated outputs for hazardous area instrumentation loops. Water treatment facilities deploy the module for SCADA system integration, while its surge immunity (4kV) protects communication lines in mining operations with frequent lightning strikes.
