Manufacturer: Pepperl+Fuchs
Description:

The Isolating Amplifier/Splitter is an essential component in industrial automation and process control systems, particularly in applications requiring explosion protection. This device serves to isolate and condition signals from 2-wire transmitters, ensuring accurate transmission of process variables while preventing ground loops and signal interference. It is designed to operate with a 24 V DC supply, making it compatible with a wide range of industrial systems.

Common applications for this product include sensor signal conditioning in hazardous areas, where it converts and splits the input signals into dual outputs of 0/4 mA to 20 mA, 0/1 V to 5 V, or 0/2 V to 10 V. With an impressive accuracy of 0.1%, it ensures precise signal processing, which is critical for maintaining system integrity and safety. The connection is facilitated via screw terminals, allowing for straightforward installation and maintenance.
