Profinet / EtherNet/IP Deterministic Networks
The IS200TDBTH6A utilizes a triple modular redundancy (TMR) architecture to maintain deterministic signal integrity across the Mark VIe I/O network. The board interfaces with three PDIO I/O packs via D-type connectors, supporting high-speed Ethernet communication with rack controllers. Its backplane bus communication velocity is optimized for sub-millisecond contact status updates, ensuring synchronized data exchange across the R, S, and T control processors. The hardware-integrated input filters provide a 12 V RMS AC voltage rejection threshold, ensuring robust noise suppression for high-density contact input arrays in electrically noisy environments.
Frequently Asked Questions
Q: Can the IS200TDBTH6A operate with a single PDIO I/O pack?
A: No. Proper operation of the TDBT terminal board requires a full set of three PDIO I/O packs to support its TMR functionality and provide adequate network redundancy. Use of a single pack will result in communication errors and incomplete I/O mapping.
Q: Is the wetting voltage adjustable on the board?
A: The board accepts an external wetting voltage source of 24, 48, or 125 V DC to supply the 24 group-isolated contact inputs. The specific voltage level must be selected based on the external field device requirements and wired to the appropriate terminal blocks.
Field Installation Guidelines
- Mounting: The board supports either flat mounting or DIN-rail installation. Ensure the structural integrity of the mounting surface to prevent vibration-induced stress on the surface-mount components.
- Network Cabling: Connect the PDIO I/O packs to the designated JR1, JS1, and JT1 connectors. Use shielded, industrial-grade Ethernet cables and ensure the cable runs are physically separated from high-voltage AC power lines to maintain signal purity.
- Grounding: Establish a robust connection between the board’s grounding terminals and the cabinet’s common ground plane. This is required to maintain the effectiveness of the onboard noise suppression and surge protection circuitry.
- Wetting Voltage Termination: Verify the voltage rating of the external wetting source before termination. Apply the source to the appropriate input groups, ensuring correct polarity to avoid damage to the input isolation barriers.
