200-510-076-114| ABB|VM600 MPC4 machinery protection card

Description

• VM600 MPC4: An online machinery protection card from the Vibro-Meter® product line, supporting real-time measurement and monitoring.

Features

• Supports multiple sensor inputs (acceleration, velocity, displacement).
• 4 dynamic signal channels and 2 tachometer (speed) channels, all individually programmable.
• Front-panel BNC connectors for easy analysis of buffered "raw" sensor signals.
• Hot-swappable, available in standard, separate circuits, and safety (SIL) versions.
