Working Principle
The working principle of the VM600 XIO16T Input/Output Module is based on advanced signal conditioning and protection technologies, serving as an intelligent interface between the XMx16 processing module and external sensors and control systems. The working principle can be divided into several key aspects:
1. System Architecture & Signal Flow
The XIO16T module is installed in the rear of the VM600 rack and connects to the XMx16 processing module (installed in the front) via backplane connectors. Sensor signals are input through connectors at the rear of the module, where they undergo signal conditioning and protection before being transmitted to the XMx16 module for digitization and processing via the backplane.
The module employs a distributed processing architecture where the XIO16T handles all analog signal preprocessing, while the XMx16 handles digital signal processing and analysis. This well-defined division of labor leverages their respective strengths, ensuring optimal system performance.
2. Signal Input Processing
Dynamic input signals are input through J3 and J4 connectors (8 channels each, 16 channels total), while tachometer signals are input through the J2 connector (4 channels). All input channels include carefully designed input circuits providing appropriate impedance matching and signal conditioning.
For voltage input signals, the module provides high input impedance (≥200 kΩ), ensuring minimal loading effect on sensor signals. For current input signals, the module uses 100 Ω precision measuring resistors to convert current signals to voltage signals for processing.
3. Signal Conditioning & Protection
Each input channel includes multi-stage filtering circuits providing anti-aliasing filtering and EMI protection. Filter characteristics are software-configurable to meet different application needs. The dynamic input frequency bandwidth is 0.10 Hz to 38 kHz (AC mode) or DC to 1.0 Hz (DC mode), and users can select appropriate high-pass filter cutoff frequencies (1.0 Hz, 3.0 Hz, or 10.0 Hz) as needed.
The module provides comprehensive overvoltage and overcurrent protection. All inputs can withstand up to ±50 V common-mode voltage and 30 V signal voltage, ensuring reliable operation in industrial environments.
4. Signal Sharing Mechanism
The XIO16T supports signal sharing within VM600 racks, which is one of its most important features. Through the backplane's Raw bus and Tacho bus, the module can share signals with other processing modules (such as MPC4Mk2/MPC4 machinery protection modules).
The Raw bus is used to share dynamic input signals, supporting up to 32 signal lines. The Tacho bus is used to share tachometer input signals, supporting up to 6 signal lines. This signal sharing mechanism greatly simplifies system wiring, reduces the need for duplicate signal acquisition, and improves system consistency and reliability.
5. Communication Interface Function
The module provides two Gigabit Ethernet interfaces, one located on the front panel (on the XMx16 module) and one on the rear panel (on the XIO16T module). These interfaces are redundant, allowing users to choose which interface to use based on actual needs.
The Ethernet interfaces use the 1000BASE-T standard, supporting data transfer rates up to 1000 Mbps. The interfaces use TCP/IP protocol to communicate with computers running VibroSight software for configuration, data acquisition, and status monitoring functions.
6. Power Management & Distribution
The XIO16T module receives operating power (+5 VDC and ±12 VDC) from the VM600 rack power supply. The power circuit includes multi-stage filtering and voltage regulation design to ensure stable and clean power supply to all parts of the module.
The module's power consumption is optimized: <14 W from the +5 VDC supply, <8 W from the +12 VDC supply, and <4 W from the -12 VDC supply, with total power consumption <26 W (combined with XMx16 module). This low-power design reduces the system's thermal load and improves reliability.
7. Status Monitoring & Diagnostics
The module provides multiple status indicators (LEDs) to display the module's operational status in real-time. The STATUS LED indicates the XIO16T module's configuration status and communication status, while the ETHERNET connector link and activity LEDs indicate the status of system Ethernet communications.
These status indication functions help users quickly identify and diagnose system issues, improving system maintainability and availability.
8. Hot-Swap Mechanism
The XIO16T module supports hot-swap functionality, thanks to carefully designed power sequencing circuits and signal isolation. When a module is inserted into a running system, the power circuit powers up in the correct sequence to avoid current surges; when a module is removed, the signal lines are disconnected before the power, preventing signal interference.
9. Mechanical & Connection Design
The module features a robust mechanical design with dimensions of 6U H × 20mm W × 125mm D and weight of approximately 0.32 kg. The connector system is specially designed, with all connectors being removable for easy installation and maintenance.
The use of B2CF plug-in connectors and dedicated crimp terminals is recommended to ensure connection reliability and consistency. The module comes with a crimp terminal kit containing 100 H0,34/12 TK terminals and 100 H0,5/16 OR terminals.
10. Environmental Adaptability
The XIO16T module is designed for harsh industrial environments, with an operating temperature range of 0 to 65°C and storage temperature range of -40 to 85°C, suitable for most industrial applications. The module is also available with an optional conformal coating version for additional protection against chemicals, dust, moisture, and extreme temperatures.
