EMERSON CON041 Interface Module

Emerson CON041 Interface Module (EPRO Eddy Current Signal Converter)

 

 

The Emerson CON041 (EPRO series) is an eddy current signal converter / interface module, mainly used in turbomachinery vibration and displacement monitoring systems. It is not a PLC interface module in the usual sense, but a sensor signal conditioning unit that works with Emerson EPRO proximity probes.

It is typically used together with PR6422 / PR6423 / PR6424 proximity sensors for measuring shaft vibration, position, eccentricity, and displacement in rotating machines like turbines, compressors, and pumps.
