Product Details
The Emerson PR6423/010-000 CON021, also cataloged as the PR6423/010-000 CON021 Eddy Current Signal Converters, operates as a dedicated hardware component for high-frequency dynamic displacement signal processing within machinery protection systems. The converter converts high-frequency eddy current sensor field variations into linear proportional analog voltage outputs for radial and axial shaft displacement monitoring.

4-20 mA HART Loop Protocol and Channel Isolation
The CON021 signal evaluation topology utilizes channel-to-channel isolation architecture to isolate sensor primary loops from processing backplanes, preventing common-mode ground loops across high-speed turbomachinery monitoring channels. When interfacing with downstream data acquisition equipment running 4-20 mA HART loop protocol transmitters or FOUNDATION Fieldbus network gateways, the signal converter maintains high analog bandwidth integrity from 0 to 20000 Hz. Built-in cold junction compensation reference circuitry stabilizes signal processing paths during ambient thermal swings within the -30 to 100 deg C operating window.
Frequently Asked Questions
Q: What power supply voltage ranges are required depending on the configured analog output span?
A: An input supply voltage of -23 V to -32 V is required for an output range of -4 V to -20 V, while an input supply voltage of -21 V to -32 V supports an output range of -2 V to -18 V.
Q: How is the transducer cable terminated at the CON021 module enclosure?
A: The transducer connects via a self-locking Lemo plug interface, ensuring a secure mechanical lock and shielded coaxial connection.
Q: What wire size limit is supported on the supply and output connection terminals?
A: The supply and output screw terminals accept stranded or solid copper wire up to a maximum cross-sectional area of 1.5 mm2.
Field Installation Guidelines
- Mount the CON021 housing onto a clean, flat metallic surface using the four supplied M5x20 screws.
- Verify that the mounting site does not exceed an IP20 rating requirement and operates within the -30 to 100 deg C temperature limit.
- Connect the eddy current transducer cable to the dedicated Lemo receptacle until the self-locking mechanism engages fully.
- Strip the power and output signal conductors, ensuring individual wire cross-sections do not exceed 1.5 mm2.
- Secure signal wires into the screw terminals according to the terminal assignment diagram, torqueing screws to standard specs.
- Connect the outer cable shielding directly to the cabinet ground grid to protect against high-frequency electromagnetic interference.
