Description
The Vibro-Meter VM600 IOC4T (part number 200-560-000-113) is a high-reliability Input/Output (I/O) Card manufactured by Vibro-Meter (Meggitt Sensing Systems / Parker Hannifin) for the VM600 Series Machinery Protection System (MPS).
Installed in the rear of a VM600 rack directly behind its corresponding MPC4 (Machinery Protection Card), the IOC4T acts as the primary signal interface bridge. It manages raw dynamic vibration inputs, speed/tachometer channels, buffered transducer outputs, analog control loops, and hardware alarm relay switching for critical turbomachinery protection.

Core Features & Operating Capabilities
- MPC4 Card Integration: Operates in slave mode, communicating directly via a high-speed Industry Pack (IP) interface with its paired front-slot MPC4 protection card to route, buffer, and process vibration signals.
- Comprehensive Signal Conditioning: Provides robust surge suppression and electromagnetic compatibility (EMC/EMI) filtering across all incoming field sensor lines and outgoing control loops.
- Buffered Raw & Processed Outputs: Exposes raw unintegrated vibration signals for diagnostic analyzers alongside software-scaled analog outputs (0–10 V or 4–20 mA) mapped directly to host DCS or SCADA systems.
- Onboard Alarm Switching: Features four local programmable alarm relays that can be assigned under software control to trip conditions, common alerts, or system fault monitoring.
- Hot-Swappable Rear Design: Engineered for live insertion and extraction within standard VM600 rack configurations (such as ABE04x or ABE056 enclosures) without interrupting adjacent channel loops.
