Overview
The Murr Elektronik 55309 is an MVK I/O Compact Module designed for robust PROFIBUS DP fieldbus integration. This metal-housed module delivers 16 configurable multifunction channels—8 digital inputs and 8 digital outputs—making it suitable for a wide range of distributed I/O applications in manufacturing, material handling, and process automation.
Key Features
- 16 Multifunction Channels: Configurable digital inputs (DI) and outputs (DO) via MVK-MP DIO8 configuration
- PROFIBUS DP Fieldbus: 12 Mbit/s transfer rate, addressing via rotary switch (1–99)
- Industrial Connectors: M12, B-coded sensor supply (5-pole) and M12, A-coded I/O ports (5-pole)
- Metal Housing, Fully Potted: Robust metal housing extremely resistant to vibration, media, and weld splatter
- IP67 Protection: Sealed against dust and water ingress
- Comprehensive Diagnostics: Per-module and per-channel diagnostic via LED and bus monitoring for under-voltage, no voltage, short circuit, overload, and cable break
