Shinkawa 2M04-500 Converter system

Overview

The Shinkawa 2M04-500 Converter System is part of SHINKAWA’s vibration/condition-monitoring lineup. It accepts inputs from SHINKAWA accelerometers and eddy-current displacement probes, conditions the signals, and delivers standard process outputs to control and protection systems. Typical deployments include integration with VM-series machinery protection racks and plant PLC/DCS for trending, interlocks, and trips. In brownfield revamps it serves as a drop-in interface between existing transducers and modern controls, simplifying lifecycle support and spares.

Key Features & Specs

• Multi-channel aggregation for plant assets (converter “main” plus function modules)

• Inputs: accelerometers (velocity/accel) and eddy-current displacement probes

• Outputs: isolated 4–20 mA (and/or 1–5 V) for DCS/PLC trending and alarm setpoints

• Industrial power (rack supply / AC mains variant) with dedicated power module

• Machine-protection topology: route to shutdown relays in the monitor rack (API 670 style architectures)

• Panel/rack mounting; field-replaceable modules; front diagnostics/LEDs (variant-dependent)

I/O & Module Variants (guide)

• 2M04-500 (Main/Converter): system backbone for channels and outputs

• 2M04-500-V: vibration/velocity/acceleration input module (with scaling to 4–20 mA)

• 2M04-500-T: transducer interface for proximity/displacement chains

• 2M04-500-S: power-supply/converter supply module for the rack

(Exact channel counts, ranges, and module mix depend on the build; confirm with your datasheet/BOM.)

Applications

• Turbine/compressor protection (radial vibration, thrust position via prox probes)

• Pump and fan condition monitoring in utilities and process units

• Boiler-feed–pump and balance-of-plant assets where multi-channel aggregation is needed

• Brownfield DCS migrations—retain probes, modernize signals to 4–20 mA/1–5 V

Installation & Commissioning Notes

• Verify transducer types, cabling and polarity; keep probe/accelerometer cables within specified lengths.

• Calibrate scaling (mm/s, µm, g) to match control-system ranges; document trip setpoints separately in the monitor.

• Provide segregated 24 VDC/AC (per variant) and cabinet grounding; observe EMC best practices.

• After I/O loop-checks, run a controlled bump test or probe-gap check to validate channels.

What’s Included / Options

• Converter main unit (2M04-500) with ordered function modules (-V/-T/-S, etc.)

• Rack hardware and terminal accessories (per order)

• Optional: spare power module, I/O module, and verified transducer cables

FAQ

Q: Is the 2M04-500 compatible with SHINKAWA VM racks?

A: Yes—it’s commonly paired with VM-series monitoring/protection systems; confirm exact rack and module mix with your BOM.

Q: What outputs are available?

A: 4–20 mA (and/or 1–5 V) for DCS/PLC integration; details are variant-dependent—check the spec for your module.

Q: How many channels can it handle?

A: Builds vary by module set. Multi-channel configurations (vibration + displacement) are typical; we’ll validate channel count from your nameplate.

Q: Can you support replacement of a single sub-module (e.g., -V, -S, -T)?

A: Yes—send the full part code and photos; we’ll match the exact module revision and lead time.
