IOC4T 200-560-000-016 is a multi-functional Input/Output Card for industrial control systems. It handles both input and output signals, ensures stable transmission, suits industrial environments, supporting efficient equipment control and monitoring.
The Meggitt VM600 IOC4T is a high-performance input/output card designed exclusively as a signal
interface for the VM600 series MPC4 machinery protection card. Engineered by Meggitt—an industry
leader in aerospace, defense, and energy sensing solutions—this card serves as the critical link
between field sensors, external control systems, and the MPC4, enabling real-time machinery
protection and condition monitoring across industrial sectors.
Ideal for power generation, oil & gas, and heavy manufacturing, the IOC4T ensures stable signal
transmission, robust EMI protection, and flexible integration. It supports hot-swappable installation
for minimal downtime and is available in "standard" and "separate circuits" versions to meet diverse
application needs.
2. Key Features & Benefits: Built for Industrial Resilience
2.1 Versatile Signal Handling
Dual Input Types: 4 dynamic (vibration) signal inputs + 2 tachometer (speed/phase) inputs, compatible with most industrial sensors and signal conditioners.
Flexible Outputs: 4 analog outputs (jumper-selectable 4–20 mA current or 0–10 V voltage) and 32 programmable open-collector digital outputs (for IRC4/RLC16 relay cards).
Buffered Raw Signals: Provides unprocessed "raw" sensor signals for advanced diagnostics, plus calibrated analog outputs for external monitoring systems.
2.2 Robust Protection & Reliability
EMI/EMC Compliance: All inputs/outputs feature EMI protection, meeting EN 50081-2, EN 50082-2, IEC 61000-6-2/4, and TR CU 020/2011 standards to resist industrial electrical noise.
Local Alarm Relays: 4 configurable relays (1 NC/NO contact each) for direct alarm triggering (e.g., MPC4 faults, sensor errors) under software control.
Safety-Certified: SIL 1 compliance (per IEC 61508) and "separate circuits" version (per IEC 60255-5) for enhanced insulation, suitable for functional safety applications.
2.3 Easy Installation & Maintenance
Hot-Swappable Design: Enables live insertion/removal without system shutdown, reducing maintenance downtime.
Screw-Terminal Connectors: 48 terminals for secure, tool-friendly wiring of inputs/outputs—no specialized connectors required.
Rotary Keying Compatibility: Ensures seamless pairing with the MPC4 card and VM600 rack (ABE04x/ABE056) for error-free integration.
