EPRO CON021/915-040 Signal Converters

The EPRO CON021/915-040, also cataloged as the CON021/915-040 Signal Converter, operates as a dedicated hardware component for eddy current signal conditioning within MMS 6000 and IMR 6000 machinery monitoring platforms.

Hardware Specifications

Gap Voltage Validation and Eddy-Current Probe Scaling

The CON021/915-040 converts high-frequency RF carrier signals from connected PR-series eddy current proximity probes into standardized analog DC output signals. Gap voltage validation targeting mid-scale negative DC targets ensures precise probe scaling across a 4.0 mm nominal measuring range with a linearity error within 1.5%. High dynamic frequency bandwidth from 0 Hz to 20000 Hz with a fast rise time under 15 us eliminates phase lag, preserving signal accuracy for dynamic shaft displacement, axial position, and speed/keypulse processing.

Frequently Asked Questions

Q: Can the CON021/915-040 module be hot-swapped during active system operation?

A: Yes, the module supports live hot-swappable insertion and removal in MMS 6000 and IMR 6000 rack enclosures without interrupting adjacent monitoring channels.

Q: How is the linear measurement range verified during field installation?

A: Verification is performed by adjusting probe mechanical gap clearance until the DC voltage output reaches the mid-scale bias voltage, establishing linear calibration over the 4.0 mm span.

Field Installation Guidelines

• Insert the converter module firmly into the designated MMS 6000 or IMR 6000 rack slot to ensure proper backplane connector engagement.
• Ensure continuous cable shielding from the non-contacting probe extension cable to the rack frame, grounding the shield at the rack end to prevent stray RF noise.
• Verify negative DC power supply levels (-21 VDC to -32 VDC) prior to powering field signal circuits.
• Separate sensor signal lines from high-voltage AC electrical lines to avoid capacitive noise coupling.
