Hardware Specifications

PLC and DCS Integration Architecture

• Backplane Bus Communication Velocity: Operates across the S800 electrical ModuleBus supporting high-speed data transmission rates up to 10 Mbps without communication degradation.
• I/O Density Scaling: Enables the extension of ModuleBus lines to connect I/O modules distributed across multiple separate DIN rails within the same cabinet or adjacent enclosures.
• Firmware Flash Compatibility: Transparent pass-through physical media requiring no active software or firmware configuration layers.
• Network Determinism: Maintains deterministic communication loops when paired with TB805, TB845, TB806, or TB846 interface units.

Ordering Information

• Integrated D-SUB 25 male and female connector ends

Field Installation Guidelines

• DIN-Rail and Connector Routing: Route the 0.3 m shielded cable carefully between adjacent DIN-rail sections, ensuring strain relief is applied to avoid stressing the D-SUB 25 connectors.
• Shielding and Grounding: Ensure both D-SUB metal hoods make solid 360-degree contact with ground reference points to maintain electromagnetic interference (EMI) suppression.
• Bending Radius Limitations: Maintain a minimum bending radius compliant with industrial shielded data cables to prevent internal conductor fracture or impedance mismatch.
• Mating Verification: Secure connector thumbscrews firmly on both male and female ends to prevent intermittent signal dropouts caused by industrial vibration.
