The PR electronics 2255B1X is a high-performance, loop-powered 4…20 mA isolator designed for demanding industrial applications. This compact 6 mm module provides reliable 1:1 signal repetition while ensuring high galvanic isolation between the input and output circuits. It effectively eliminates ground loop problems, protects sensitive equipment from transient voltages, and maintains signal integrity in complex process control systems. The 2255B1X is powered by the input loop, eliminating the need for an external power supply and simplifying installation. With its fast response time and excellent accuracy, it is an ideal solution for isolating analog current signals in a wide range of automation environments, including those requiring ATEX/IECEx certification for hazardous locations.
