Overview
The Murrelektronik 857833 from the MPS series is a high-performance input filter designed to improve signal quality and protect sensitive automation equipment from electrical disturbances. It removes unwanted noise from AC input lines, ensuring stable and reliable operation in harsh industrial environments.
Moreover, the filter provides strong suppression across a 20 Hz to 1 MHz frequency range, making it ideal for PLC systems, sensors, actuators, and industrial communication devices. In addition, its compact, lightweight, and panel-mountable design allows easy integration into control cabinets where space efficiency is essential.
Therefore, the 857833 is widely adopted in automation panels requiring high-performance noise reduction and long-term system stability.
