Product Details
Configured for high-frequency coaxial signal routing and redundant bus interconnection in Foxboro I/A Series networks, the Foxboro P0912CM (P0912CM Dual Coax Cable) provides direct physical/electrical execution. It establishes dual-channel coaxial communications between nodebus extension interfaces, local sub-racks, and control processor assemblies.

Cold Junction Compensation and Loop Signal Isolation
The Foxboro P0912CM incorporates high-density double-braided shielding across both coaxial channels to maintain low signal attenuation and suppress high-frequency electromagnetic interference. By preserving signal ground continuity across local bus segments, the cable prevents common-mode noise propagation into analog input channels executing cold junction compensation (CJC) algorithms and 4-20 mA HART loop protocol telemetry.
Frequently Asked Questions
Q: What network function does the P0912CM dual coax cable serve within a Foxboro I/A Series architecture?
A: The P0912CM provides dual-channel coaxial signal routing to interconnect redundant system nodes, baseplates, or bus extension modules.
Q: Does the P0912CM cable assembly require external impedance matching terminators?
A: The cable is manufactured to exact impedance specifications for Foxboro coaxial bus interfaces; termination requirements depend on baseplate position within the bus segment layout.
Field Installation Guidelines
When laying the P0912CM dual coaxial cable, ensure connectors are fully aligned and hand-tightened to baseplate BNC/coaxial headers before securing lock rings. Maintain a minimum bend radius of 10 times the outer cable diameter to avoid crushing or altering the internal dielectric spacing.
Route dual coaxial lines inside low-voltage wiring troughs, separated from high-power AC distribution circuits and motor drives. Connect cable shields to the primary cabinet single-point ground bus per system layout documentation. Where cabinet penetrations require threaded conduit fittings, ensure all NPT connections achieve 5 full threads of engagement.

Understanding Siemens PLC Memory Cards: MMC, SMC, and SD Solutions in Industrial Automation
Memory management plays a pivotal role in maintaining control system reliability across modern manufacturing plants. Industrial control systems rely on specialized memory cards to store project logic, firmware updates, and retentive system data. Siemens uses several memory architectures, including Micro Memory Cards (MMC) and SIMATIC Memory Cards (SMC). Engineers must understand these hardware variations to ensure zero data loss and minimize downtime during maintenance routines.
Redefining Control Systems: The Rise of Flexible I/O Modules in Industrial Automation
Conventional input-output architectures often limit engineering agility and inflate long-term inventory costs. Today, Flexible Input/Output Modules (FIOM) are transforming how control system engineers design, commission, and maintain automation infrastructure. By allowing individual channel software configuration, FIOM technology bridges the gap between rigid hardware design and dynamic plant requirements.
Understanding Modern SCADA Systems: Architecture, Communication Topologies, and Industrial Applications
Supervisory Control and Data Acquisition (SCADA) systems form the digital backbone of modern industrial automation. They collect critical field data, transmit signals across vast distances, and empower plant operators with real-time process visibility.
