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.
