Product Introduction

The VMS Machine Monitoring System (MMS) VMRS 200W series is a simple monitoring system.
It converts a vibration input signal to a user-defined broadband value proportional to RMS of vibration velocity,
acceleration or True Peak-To-Peak of displacement.

The standard model provides 4 inputs from ICP accelerometers or proximity probes. Each channel provides 1 Alert relay,
1 Danger relay and 4 to 20 mA output suitable for Process Control system (DCS or PLC).

On the front panel , there are live bar graph displays with Alert and Danger levels. The buffered vibration raw signals are accessible from the front panel BNC connectors and inside Terminal Block.

Features

• Up to 4 of Dynamic simultaneous monitoring
• With Alert and Danger as two independent set points and contact relay outputs for each channel
• Selectable Individual channel live bar-graph displays
• Programmable Alert or Danger Level
• Isolated 4-20mA output signals (Optional)
• Buffered raw output signals
• API 670 compliant
