Emerson 38B6041X152 Genuine Standard I/P (Current-to-Pressure) Converter Assembly

Frequently asked questions
Q:What is the Emerson Fisher 38B6041X152?
A:The Emerson Fisher 38B6041X152 is a genuine I/P Converter Kit for Fisher FIELDVUE™ digital valve controllers. It is supplied as the standard-temperature version and is identified by Emerson as a recommended spare part for controller maintenance.

Q:What is the function of the 38B6041X152 I/P Converter Kit?
A:The I/P Converter Kit services the electro-pneumatic conversion section of the digital valve controller, converting the controller's electrical signal into a pneumatic output used to position the control valve.

Q:Is there an extreme-temperature version of the I/P Converter Kit?
A:Yes. Emerson offers 38B6041X132 as the extreme-temperature version, which includes fluorosilicone elastomers for applications requiring extended temperature capability.

Description

The Emerson Fisher 38B6041X152 is a genuine I/P Converter Kit designed for use with Fisher FIELDVUE™ digital valve controllers, including the DVC6200, DVC6200p, and compatible DVC6005 models. Identified by Emerson as a recommended spare part, the kit is intended for servicing the electro-pneumatic conversion section of the digital valve controller, where the input electrical control signal is converted into a pneumatic output for valve actuation. It is supplied as the standard-temperature version with nitrile elastomer components, while a separate extreme-temperature version is available for applications requiring fluorosilicone elastomers. The I/P Converter Kit is manufactured to the original Fisher specifications, ensuring proper fit, compatibility, and performance during maintenance or replacement of compatible FIELDVUE instruments. Emerson recommends using only genuine Fisher replacement parts to maintain the controller's operating performance, reliability, and product warranty. The 38B6041X152 is listed in the official FIELDVUE spare parts documentation for routine maintenance and lifecycle support of Fisher digital valve controllers used in industrial process control applications.

Application areas

The Fisher 38B6041X152 I/P Converter Kit is a vital electro-pneumatic module used inside Emerson FIELDVUE™ DVC6200, DVC6200p, and DVC6005 digital valve controllers. Because this kit features standard nitrile elastomer seals, its application areas are primarily defined by standard temperature ranges across automated continuous processing plants:

• Oil and Gas Production & Refining: Applied in upstream wellhead controls, midstream separation units, and downstream refinery blending blocks.
• Chemical and Petrochemical Plants: Managing control valve actuation across volatile or corrosive chemical processing pipelines.
• Power Generation Facilities: Regulating boiler feed water systems, steam bypass loops, and gas turbine fuel supplies.
• Pulp, Paper, and Water Treatment: Maintaining precision control over water filtration networks, stock-flow processing, and chemical additive loops.
