Shinkawa VM-5F-910-000-110-331-00 Dual-channel Vibration Monitoring Module

SHINKAWA VM-5F-910-000-110-331-00 Dual-channel Vibration Monitoring Module Details
I. Basic Positioning
This product is the VM-5 series dual-channel shaft vibration monitoring card from Japan’s Shinkawa (SHINKAWA), belonging to the core component of the turbine TSI unit protection system. It strictly follows the API 670 industrial machinery protection standard and is mainly used for real-time monitoring of shaft vibration in key rotating equipment such as power plant turbines, oil and gas industry compressors, and large pump sets. This model has entered the end-of-life (EOL) stage, and the market mainly relies on inventory spare parts and second-hand maintenance replacements.
Model Segmentation Explanation
VM-5K: Basic model = Dual-channel vibration monitoring module; the suffix VM-5F-910-000-110-331-00 is a customized configuration code, defining the measurement range, power supply specifications, alarm thresholds, output type, and compatible probe specifications.

Core Hardware & Functional Parameters
Sampling Channels
Dual-channel independent monitoring (CH1/CH2), single channel can set 4 levels of alarm thresholds (warning / dangerous classification), compatible with the PS-5K series eddy current displacement probe for collecting radial shaft vibration, the conventional measurement range is 0-500μm (peak-to-peak), the range can be adjusted on-site.
Signals and Outputs
Standard industrial transmitters: Each channel supports 4-20mA isolated analog output, connected to DCS/PLC for collection;
Relay contact output: Graded alarm switch quantity, directly linking to the unit interlock shutdown;
The panel is equipped with a BNC buffer test port, which can be externally connected to an oscilloscope to observe the original vibration waveform;
Built-in self-check function, probe break, signal abnormality automatically trigger fault alarm.
Operation Design
The front panel integrates numerical display, parameter keys, no need to stop the machine to modify thresholds, view real-time vibration values, probe clearance voltage, convenient on-site debugging and maintenance; supports rack slot installation (compatible with VM-5 series 8/10 slot cabinets), or can choose standalone complete machine model.
Applicable Scenarios
Monitor the radial shaft vibration and bearing seat vibration of rotating equipment, widely used in thermal power / nuclear power turbine units, gas turbines, oil and gas refining centrifugal compressors, large industrial pumps; the module can be combined with the same series speed and axial displacement card components to build a complete TSI monitoring system.

Accessories and Usage Tips
Compatible Accessories: Must be paired with Shinkawa original factory eddy current probes (PS-5K), and use dedicated extension cables for calibration, mixed use of third-party probes will cause measurement deviation;
Power Supply Specifications: Industrial standard 24VDC power supply, some customized models are compatible with centralized power supply of cabinets;
Current Status Warning: The original factory has stopped production, priority purchase should be made from regular inventory spare parts, or the same brand VM-7 series new module for upgrade replacement; maintenance wiring requires full power-off, the shielding layer of the cable should be single-point grounded according to the specification to avoid industrial site interference.

Reference for Replacement in the Same Series
Upgrade preferred VM-25 compact type, VM-7 series vibration monitoring module, hardware compatibility is stronger, supports digital communication, suitable for new and old unit renovation scenarios.
