Function:Convert weak coil signal from PR6424 eddy current probe into standard voltage signal,realize signal demodulation and conditioning.Transmit processed signal to MMS monitoring module for vibration and displacement calculation,alarm and protection interlock.
Installation:DIN rail installation inside control cabinet.Connect Lemo port to PR6424 probe,terminal block for -24V power supply and signal output.
Interface:
‑Lemo coaxial port for eddy current probe connection
‑Screw terminal block for power and analog signal output
‑LED indicator for power and fault status
Circuit feature:High precision signal demodulation circuit,built-in cable break/short circuit self-diagnosis,reverse polarity protection,strong anti-electromagnetic interference.
Feature:EPRO CON021 preamplifier,part number 9200-02061n,calibrated matching for PR6424 16mm probe. The preamplifier and probe must be used as a complete calibrated measuring set. Common faults:internal circuit burnout,connector pin corrosion,signal drift. Confirm matched probe model before replacement.
Diagnostic:Preamplifier failure causes abnormal gap voltage,signal loss,TSI channel alarm,losing shaft vibration and displacement monitoring.

Built‑in function
9200-02061n(CON021) conditions eddy current probe signal for large rotating machinery protection system,widely used for power plant TSI spare replacement.
Product Brief
9200-02061n belongs to EPRO eddy current measuring chain family,CON021 preamplifier dedicated for PR6424 16mm probe. Must use together with corresponding calibrated probe. Verify probe model and TSI card compatibility before ordering. Check power supply and signal output function during commissioning. Widely applied for steam turbine,compressor and generator condition monitoring. ESD anti‑static protection shall be followed during installation.
