Foxboro Schneider Electric P0916DB I/A Series Fiber Optic Fieldbus Expansion Cable
The Foxboro P0916DB is a high-performance fiber optic expansion cable for the I/A Series DCS. It provides a noise-immune, high-speed data link between Fieldbus Modules and controllers, ensuring reliable long-distance communication and deterministic control in demanding industrial environments.
The Foxboro P0916DB functions as a high-speed fiber optic expansion cable designed for the I/A Series (Intelligent Automation) distributed control system. This specialized cable facilitates the critical data link between Fieldbus Modules (FBM) and the Field Control Processors (FCP) over extended distances. Because industrial plants often cover large areas with significant electromagnetic interference, the P0916DB utilizes fiber optic technology to ensure that process data remains immune to electrical noise and ground loops.
Furthermore, this cable supports the expansion of the high-speed Fieldbus, allowing engineers to distribute I/O clusters closer to the field equipment while maintaining centralized control logic. The P0916DB features ruggedized connectors designed for the high-vibration and chemically diverse environments found in processing facilities. Since it provides a deterministic communication pathway, the cable ensures that time-critical control signals reach their destination without latency. Consequently, the P0916DB plays a vital role in maintaining the reliability and scalability of the Foxboro Evo and I/A Series architectures.

PLC and Control Network Integration
Backplane bus communication velocity and deterministic synchronization for the Series 90-30 system are facilitated through the effective routing of serial data. Firmware flash compatibility within the host modules is supported, ensuring that the physical signal path provided by the IC693CBL305 maintains high integrity across logic execution cycles. Furthermore, I/O density scaling and port configuration are optimized via this hardware split, enabling the PLC to process communication packets without signal cross-talk. When utilized in complex automation architectures, the cable acts as a protocol bridge, ensuring that RS-232 and RS-485 signals are routed to their appropriate logical destinations on the coprocessor.
Frequently Asked Questions
Q: Does the IC693CBL305 cable support active signal buffering or protocol conversion?A: No. The IC693CBL305 is a passive wiring accessory designed specifically for physical port splitting. It does not contain active electronic components for signal amplification or protocol translation.Q: Can the cable be used to connect different electrical standards on Port 1 and Port 2 simultaneously?A: The cable is configured to route signals from the combined host connector to the designated 25-pin outputs. While Port 1 supports RS-232 and Port 2 supports RS-232 or RS-485, the limitation is defined by the host coprocessor module's internal configuration, not the cable itself.
Field Installation Guidelines
Inspect the connectors for bent pins before insertion into the CMM or PCM module ports.
The right-angle connector must be fully seated into the host module port to ensure consistent electrical contact.
Ensure the dual 25-pin connectors are properly identified and labeled as Port 1 and Port 2 during installation to avoid configuration errors.
Secure the cable using standard cable ties to prevent mechanical strain on the host module ports, as excessive tension can lead to intermittent signal loss in industrial environments.
