Profinet / EtherNet/IP Deterministic Networks
The IS200TSVOH1BCC provides the physical interface layer for high-speed valve actuation. It integrates Simplex and TMR signal topologies, ensuring that position measurement data and trip signals remain deterministic across the Mark VI bus. The board utilizes advanced surface mount technology to maintain signal integrity for sensitive LVDT feedback loops, providing the stable 3.2 kHz excitation frequency required for precise valve position tracking. Firmware flash compatibility ensures that the board remains compliant with updated control logic within the Mark VI network architecture.
Frequently Asked Questions
Q: Does this terminal board support redundant LVDT feedback configurations?
A: Yes, the TSVO board is architected to handle multiple feedback inputs, allowing for the integration of TMR (Triple Modular Redundant) LVDT signals to ensure valve position accuracy and system fault tolerance.
Q: Are there specific grounding requirements for the LVDT excitation output?
A: Proper shielding is required for all LVDT cabling. The shield must be terminated at the designated ground stud on the board to prevent noise injection into the 3.2 kHz excitation circuit, which could otherwise cause instability in valve positioning.
Field Installation Guidelines
- Ensure the control cabinet is de-energized and appropriate lockout procedures are followed before accessing the VME rack.
- Mount the board using the provided standoffs to ensure adequate clearance and prevent shorting against the cabinet chassis.
- Verify that all field wiring for the 8 inputs and 8 outputs is correctly landed according to the system wiring diagram to prevent damage to the servo drive circuitry.
- Ensure the 24 V DC power supply is stable and correctly connected to the primary power input terminals.
- Inspect all LVDT and PR pickup connections for integrity and proper shielding termination to mitigate EMI interference in the servo valve control loop.
