Description

The Emerson Fisher 38B6041X152 is a current-to-pneumatic (I/P) converter assembly.Its core mechanism relies on an electromagnetic force balance system: the positioner's main board sends a 4-20mA electrical current to an internal coil, creating a proportional magnetic force that moves a deflector flapper relative to a nozzle. 

This movement alters the restriction of air exhaust through the nozzle, converting the electrical input into a proportional pneumatic pressure signal (typically 0.2 to 1.0 bar). The module integrates a high-gain pneumatic relay that amplifies these subtle pressure changes into a robust air output, driving the pneumatic valve actuator to achieve highly accurate valve stem positioning.

Overview Manuals Application Notes Product Applications Insertion & Replacement Steps

Features:

  • Converts 4–20 mA electrical signals to proportional pneumatic pressure
  • Standard-temperature version with nitrile elastomers
  • Includes I/P converter assembly and protective shroud
  • Factory-approved maintenance kit
The Emerson Fisher 38B6041X152 I/P Converter Kit (Standard) is a factory replacement service kit used to restore the performance of FIELDVUE digital valve controllers. The I/P converter is a critical component that translates a 4–20 mA control signal from a distributed control system (DCS) or programmable logic controller (PLC) into a proportional pneumatic output used to position pneumatic control valves accurately.

Designed as a genuine Emerson spare part, the kit includes the I/P converter assembly and associated components required for maintenance. Standard kits utilize nitrile elastomers, while applications involving extreme temperatures require the alternate 38B6041X132 kit with fluorosilicone elastomers.

The 38B6041X152 Emerson I/P Converter Kit may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Emerson 38B6041X152 I/P Converter Kit Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The kit includes the converter assembly, mounting hardware, seals, and necessary accessories for installation. Output ranges are configurable for 3 to 15 psi or 6 to 30 psi depending on actuator requirements. Supply air pressure ranges from 20 to 150 psi.
Performance specifications include ±0.5% linearity, ±0.2% hysteresis, and ±0.1% repeatability. Response time is less than 1 second for a 10% step change. Air consumption is 0.2 SCFM typical at mid-range.
The 38B6041X152 operates in temperatures from −40°C to +85°C and is rated for 0% to 100% condensing humidity. It carries FM, CSA, ATEX, IECEx, and CE certifications for hazardous and general purpose applications.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Safety First: Ensure the valve is isolated and the actuator is depressurized before beginning. Relieve all supply pressure and wear appropriate protective gear.
Access the Module: Unscrew the cover of the digital valve controller to access the module base assembly.
Remove Old I/P Assembly: Disconnect any internal pneumatic tubes/connections. Remove the screws securing the old I/P converter to the module base.
Insert New Module (38B6041X152): Ensure the mating surfaces are clean. Align the new I/P assembly and carefully insert it into the module base.

Technical notes

The Emerson 38B6041X152 Fisher I/P Converter Kit (Standard) is a genuine replacement kit for FIELDVUE digital valve controllers, providing a 4–20 mA current-to-pneumatic conversion assembly for precise valve positioning. Featuring nitrile elastomers and direct compatibility with selected DVC6000/DVC6200-series controllers, it ensures reliable pneumatic control performance in industrial process automation

FAQs

  • What is the function of the 38B6041X152?

    +
    It converts a 4–20 mA electrical control signal into proportional pneumatic output, allowing digital valve controllers to accurately adjust the position of a control valve
  • What equipment is this part compatible with?

    +
    This kit is designed for Fisher FIELDVUE digital valve controllers, most notably the DVC6000 and DVC6200 series.
  • We have a process line running in a sub-zero Arctic environment where ambient temperatures drop below -40°C (-40°F). Can we use this standard 38B6041X152 assembly, or do we need to specify a different factory variation?

    +
    No, the standard 38B6041X152 module is restricted to standard temperature envelopes because it utilizes standard nitrile/fluorocarbon elastomeric seals. For extreme low-temperature installations dropping down to -52°C (-62°F), you must specify part number 38B6041X132. The X132 variant contains specialized fluorosilicone O-rings and an adapted internal diaphragm engineered to maintain elasticity and prevent brittle air leaks under severe frost conditions.
  • What is the difference between the 38B6041X152 and 38B6041X132?

    +
    The 38B6041X152 is the standard I/P converter assembly. The 38B6041X132 is an alternate part number explicitly intended for the "Extreme Temperature" operational option.
