Introduction
1.Core Functions
This 4-channel monitor module receives raw signals from proximity probes, velocity sensors and accelerometers, performs signal conditioning, calculation and alarm comparison for rotating machinery protection. Channels are configured in pairs via 3500 rack configuration software.www.plcva.com
- Multi-type sensor signal acquisition & conditioning Accept input from eddy current proximity probes, seismic velocity transducers and accelerometers; filter noise, normalize signal level.
- Multi-dimensional mechanical parameter calculation Each channel can be configured to measure:
- Radial vibration (shaft relative vibration)
- Thrust / axial position
- Differential expansion (differential growth)
- Shaft eccentricity
- Velocity, acceleration
- Shaft absolute vibration, Circular Acceptance Region (CAR)
- Alarm threshold comparison & relay output Two-level alarm: Alert (pre-warning) and Danger (trip). Continuously compare real-time measured value against preset setpoints. When exceeding threshold, trigger hardware relay dry contact signals for DCS / ESD interlock to shut down the machine and avoid catastrophic failure.
- Analog & dynamic buffered output
- 4–20mA analog output per channel, transmit measured value to PLC / DCS
- Buffered raw dynamic AC signal output for external spectrum analysis and fault diagnosis
- Diagnostic & status indication Front panel LED & bar graph display for channel status, OK / fault / alarm indication. Built-in sensor fault detection (probe break, short circuit, cable fault).
- Data communication Transmit static measurement values, alarm status and fault information to 3500 system host, HMI and plant network.plcva.com

2. Applications & Purpose
Core Purpose
It is a safety protection module for critical rotating equipment. It continuously monitors rotor vibration and position parameters, detects abnormal mechanical conditions at early stage, issues warning or equipment trip signal, to protect high-value rotating machinery and prevent major mechanical damage. It complies with API 670 machinery protection standard.plcva.com
Typical Equipment & Industries
- Power industry: Steam turbine, gas turbine, generator
- Oil & gas / petrochemical: Centrifugal compressor, screw compressor, high-pressure pump
- Heavy industry: Large fan, blower, gearbox
- Paper, metallurgy: Large rotating mill equipment
Working flow
Proximity / seismic sensor → 3500/42M module signal conditioning → calculate vibration / displacement static value → compare with Alert / Danger setpoints → output 4-20mA to DCS + relay alarm/trip signal → send data to monitoring HMI; meanwhile buffered dynamic signal for spectrum analysis for predictive maintenance.plcva.com
