Functional Overview

This module powers proximity probes and converts their signals into displacement values. Therefore, it supplies shaft position and vibration data to the protection processor. The 1034549-20 also filters electrical noise that would otherwise distort readings. Meanwhile, its onboard energy storage stabilizes signals during transient voltage fluctuations.

Installation and Handling Notes

Always verify probe gap voltage before connecting sensors to the 1034549-20. In addition, use low-noise coaxial cable to protect signal integrity. Tighten all connectors fully to prevent intermittent data loss. Finally, confirm channel readings during commissioning.
