The Foxboro P0927AQ, also cataloged as the P0927AQ FPS Power Cable, operates as a dedicated hardware component for AC auxiliary mains power distribution within Foxboro I/A Series DCS platforms. Designed for dual-voltage 110/240 VAC power feeds, this assembly connects line power directly to Field Processor System (FPS) power modules, enabling continuous bus energization across industrial control cabinets.

The Foxboro P0927AQ supplies isolated AC power to FPS modules powering underlying I/A Series field bus card sub-racks. While feeding primary AC voltage, internal channel-to-channel isolation within downstream FBM signal modules prevents common-mode noise from coupling back into field loop channels. Overlaid 4-20 mA HART loop protocol signals remain stable due to low thermal dissipation and shielded conductor routing inside high-density automation enclosures.
Q: Can the P0927AQ power cable be connected or disconnected while the FPS power supply module is energized?
A: Technicians must isolate the main AC circuit breaker prior to connecting or disconnecting the P0927AQ power cable assembly to prevent electrical arcing across high-voltage pin terminals.
Q: How does the cable handle dual-voltage supply changes between 110 VAC and 240 VAC systems?
A: The physical cable structure supports both 110 VAC and 240 VAC line voltages without requiring internal jumpers or external voltage adapters, provided the downstream FPS power module matches incoming line levels.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
