- Relative Humidity: ≤ 90% non-condensing
- Protection Rating: IP30, aluminum reinforced housing
Functional Features:
- 13 differential inputs each with a DAC for bias adjustment, removing DC content to center the A/D input range
- Dual Ethernet redundancy: if one network fails, operation continues uninterrupted and the fault is indicated through the active network
- Processor application code contains all logic for single or dual Ethernet operation
- Visual diagnostic LEDs for power, link, and transmit/receive status
- High-speed data transmission over Ethernet with configurable frame rates
Application Scenarios:
- Gas and steam turbine vibration monitoring and protection
- Machinery condition monitoring in power generation plants
- Compressor and pump vibration surveillance in oil and gas facilities
- Predictive maintenance systems requiring proximity and seismic signal acquisition
Performance Parameters:
- High-resolution A/D conversion for accurate vibration signal capture
- Supports multiple sensor technologies on a single pack
- Deterministic Ethernet communication with frame rates up to 100 Hz
- Low power consumption suitable for distributed I/O nodes
Material and Structural Characteristics:
- Industrial-grade PCB with processor, acquisition, and sub-board assemblies
- Aluminum reinforced housing for EMI shielding and mechanical protection
- DC-37 pin connector designed for direct mating with TVBA terminal board
- Conformal coating available for harsh-environment variants
Working Principle: The pack receives analog vibration and proximity signals from sensors connected via the TVBA terminal board. The acquisition board conditions and digitizes these signals, while the DAC on each channel adjusts bias to optimize A/D range. The processor board packages the data into Ethernet frames and transmits them to the Mark VIe controller over one or both I/O Ethernet networks, with redundant path logic ensuring continuous operation. Installation Requirements:
- Secure the TVBA terminal board first
- Plug the PVIB I/O Pack directly onto the terminal board connector
- Mechanically fasten the pack using the stud near the Ethernet ports
- Connect one or two Ethernet cables; when using dual connections, ENET1 should connect to the R controller network
- Insert the side power connector to supply the pack
- Configure the I/O Pack using ToolboxST
- Verify the N28 power sub-board is correctly seated in the TVBA connector
Usage Notes:
- Verify sensor type compatibility per channel before wiring
- Use shielded twisted-pair cabling for sensor connections to minimize noise
- Inspect LED indicators regularly for link and power status
- Avoid applying lateral force on the DC-37 connector during installation or removal
- Confirm frame rate configuration matches controller requirements
