Honeywell 20VR6 Replacement/Upgrade Solution for 20VR

Product Overview

Honeywell 20VR6 Replacement/Upgrade Solution for 20VR Series: Seamless Transition from Legacy EMI Filtering Systems

The Honeywell 20VR6 is a 20A single-phase EMI power line filter designed for industrial control panel environments where electromagnetic interference suppression is critical to system stability. As legacy installations built around the Honeywell 20VR series approach end-of-service milestones, plant engineers and procurement teams are actively seeking verified replacement and upgrade paths that minimize downtime, preserve wiring layouts, and maintain compliance with EMC directives. The 20VR6 addresses all of these requirements directly, offering a drop-in compatible solution for a wide range of discontinued or aging EMI filter models across industrial automation platforms.

Whether your facility is retiring an older Schaffner FN2010, a Murr Elektronik 10500 series filter, or a legacy Epcos B84143 line filter installed in a Siemens or Allen-Bradley control cabinet, the 20VR6 provides equivalent attenuation performance in the same compact form factor. Its stud terminal connection method is compatible with standard DIN rail-mounted terminal blocks and panel-mount wiring harnesses, eliminating the need to re-route conductors or modify existing cable trays during retrofit.

Seamless Upgrade Solutions

A successful EMI filter retrofit rarely involves a single component swap. In most industrial control cabinet modernization projects, the 20VR6 is installed alongside a broader set of upgrades to ensure the entire power distribution and signal conditioning chain meets current EMC and safety standards.

When replacing the line filter in a Siemens S7-300 or S7-400 control system, engineers typically also address the 24VDC power supply module — units such as the Siemens SITOP PSU100S or equivalent Phoenix Contact QUINT-PS series — to ensure the filtered AC input feeds a regulated, noise-free DC bus. In Allen-Bradley CompactLogix or MicroLogix installations, the 20VR6 is commonly paired with a 1492-CABLE wiring system and 1492-IFM interface module to maintain clean signal integrity from the filtered supply through to the I/O backplane.

For systems using Profibus DP or Modbus RTU communication backbones, the EMI filter upgrade is often coordinated with a replacement of the communication module — such as a Siemens CP 342-5 Profibus module or a Schneider Electric TSXSCP114 serial link module — to eliminate ground loop interference that legacy filters no longer adequately suppress. In Mitsubishi MELSEC Q-series or iQ-R series control panels, the 20VR6 is frequently installed upstream of the QJ71PB92D Profibus master module to protect sensitive fieldbus communication from conducted EMI on the AC supply line.

Control cabinet retrofits also commonly involve replacing aging terminal blocks with Phoenix Contact PTFIX or Weidmüller Klippon series modular terminal systems, which integrate cleanly with the stud terminal connection of the 20VR6 and simplify future maintenance access. Where signal isolation is required between the filtered supply and analog I/O channels, a WAGO 857 series signal conditioner or equivalent DIN-rail-mounted isolator is typically added to the upgrade bill of materials.

In variable frequency drive (VFD) applications — particularly Danfoss FC302, ABB ACS880, or Yaskawa GA700 installations — the 20VR6 serves as the input line filter on the AC supply side, replacing discontinued OEM-specified filters that are no longer available through the original manufacturer’s service channel. This is a common scenario in pump, fan, and conveyor retrofit projects where the drive itself is retained but the ancillary components require modernization.

Retrofit Guidance FAQ

Q: Can the 20VR6 be wired directly in place of my existing 20VR series filter without modifying the cable harness?
A: Yes. The 20VR6 uses the same stud terminal configuration as the standard 20VR series, allowing direct conductor re-termination without re-routing. Verify conductor cross-section compatibility (typically 4–6mm² for 20A circuits) and torque the stud terminals to the specified value per the installation datasheet.

Q: Does replacing the EMI filter require any PLC program changes?
A: No. The 20VR6 is a passive power conditioning component and has no interface with the PLC program, I/O configuration, or communication stack. No software changes, tag remapping, or firmware updates are required.

Q: Is the 20VR6 compatible with both Profibus and Ethernet/IP communication environments?
A: Yes. As a passive AC line filter, the 20VR6 is protocol-agnostic. It conditions the AC supply upstream of all active components and does not interact with fieldbus or industrial Ethernet layers. It is equally effective in Profibus DP, Modbus TCP, EtherNet/IP, and PROFINET environments.

Q: Will the 20VR6 fit in the same panel cutout as my existing filter?
A: The 20VR6 is designed to the standard 20VR series mechanical envelope. In most cases it fits the existing panel cutout and mounting hole pattern without modification. Confirm the exact chassis dimensions against your panel drawing before installation if the existing filter is from a third-party equivalent.

Q: What is the recommended procedure for commissioning after installation?
A: After installation, perform an insulation resistance test on the AC supply circuit, verify correct phase and neutral orientation at the stud terminals, and conduct a functional power-on test with the downstream load disconnected. Measure leakage current to confirm compliance with your site’s safety requirements before reconnecting the control system.

Warranty Assurance

Every Honeywell 20VR6 unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to dispatch, each unit undergoes outgoing quality inspection including visual examination, terminal integrity check, and basic electrical continuity verification. Units that do not pass inspection are quarantined and not shipped.
