EPRO CON021/914-080 Eddy Current Signal Converter

Configured for shaft displacement, position, eccentricity, and speed measurement in critical turbomachinery platforms, the Emerson CON021/914-080 (CON021 Eddy Current Signal Converter) provides direct physical/electrical execution. The hardware converts analog eddy-current probe inputs into continuous voltage signals across a wide dynamic frequency range of 0 to 20,000 Hz.

4-20 mA HART Loop Protocol and DCS Connectivity

The CON021/914-080 utilizes high-speed active conversion electronics featuring a rise time under 15 us to output continuous dynamic signals to plant control systems. Channel-to-channel isolation safeguards signal paths against field loop ground potential variations, preventing transient noise interference from corrupting raw vibration telemetry. The converter conditions raw probe impedances into calibrated linear voltage swings directly compatible with downstream 4-20 mA HART signal transmitters and centralized DCS networks, including Emerson DeltaV and Ovation platforms. Integrated temperature compensation algorithms maintain linear gain stability across the full operating window of -30 deg C to +100 deg C.

Frequently Asked Questions

Q: How is the transducer cable physically attached to the CON021 converter housing?

A: Transducer connection is executed via an integrated self-locking Lemo-plug interface, while power supply and signal output wiring utilize screw terminals supporting up to 1.5 mm2 wire cross-sections.

Q: What are the primary supply voltage options and their corresponding signal output ranges?

A: A supply input of -23 VDC to -32 VDC generates an output span of -4 VDC to -20 VDC, whereas a supply input of -21 VDC to -32 VDC yields an output span of -2 VDC to -18 VDC.

Field Installation Guidelines

1. Fasten the ALMgSi 0.5 F22 aluminum housing inside an IP-rated field enclosure using the four supplied M5x20 mounting screws.
2. Insert the transducer connection cable firmly into the self-locking Lemo-plug receptacle until the mechanical lock engages completely.
3. Strip power and output signal conductors to proper stripping length and secure them in the screw terminal block (maximum 1.5 mm2 wire size).
4. Route signal cables inside dedicated grounded metal conduits separated from AC power conductors to prevent high-frequency noise injection.
5. Connect cable shield drains directly to the single-point cabinet instrument earth ground to maintain noise suppression performance.
