Foxboro P0924JH Compact Power Supply – Stable backplane power for Foxboro Compact/200 Series I/O

The Foxboro P0924JH Compact Power Supply is designed to feed regulated DC power to Foxboro compact baseplates and I/O modules, keeping your control nodes running consistently. From my experience with Foxboro I/A Series and Compact/200 Series installations, this power unit is typically used where cabinet space is tight, redundancy is expected, and downtime simply isn’t acceptable. You might notice that it emphasizes clean, low-noise power for FBM/Compact I/O rails, which—in many cases—translates to fewer nuisance trips and more predictable module life.

Technical Specifications

Application Fields

The P0924JH is typically found in Foxboro DCS nodes where compact I/O and FBM modules are installed. It suits:

• Oil & Gas – compact wellhead RTU panels or ESD interface cabinets needing redundant low-noise power.
• Chemical & Petrochemical – high channel-density I/O marshalling with strict uptime targets.
• Power Generation – turbine auxiliary systems and balance-of-plant skids where cabinet depth is limited.
• Water & Wastewater – remote stations powered by 24 VDC with clean backplane supply to I/O.
• Pharma & Food – clean-room cabinets where stable electronics power reduces batch interruptions.

“We paired two P0924JH units on a compact baseplate to support ~40 I/O points; switchover was seamless during a DC supply changeover.” — Maintenance Supervisor, specialty chemicals

Advantages & Value

• Reliability – Clean, regulated power for FBM/Compact I/O helps cut module resets and intermittent faults.
• Compatibility – Designed for Foxboro compact baseplates, so wiring and mounting are straightforward.
• Redundancy options – Dual-supply configurations reduce risk during maintenance and DC source transfers.
• Cost control – Compact footprint lowers cabinet size; less heat typically means fewer cooling upgrades.
• Supportability – Clear status indication and simple DC feed simplify troubleshooting and spares stocking.

Installation & Maintenance

• Cabinet & mounting – Install on the intended Foxboro compact baseplate inside a clean, ventilated control cabinet. Maintain 25–50 mm free air space around the module where possible.
• Wiring – Feed with a stable 24 VDC source (sized per load, with proper fusing). Use correctly sized conductors and tighten terminals to the recommended torque.
• Redundancy – For critical nodes, deploy two P0924JH units with dual DC feeds from independent breakers. Verify load sharing and switchover behavior during FAT/SAT.
• Grounding – Bond cabinet and backplane grounds to plant earth to minimize noise coupling into I/O circuits.
• Routine checks – Quarterly visual inspection for connector looseness, dust buildup, and LED status. Keep vents clean; avoid corrosive atmospheres.
• Firmware – No user firmware for the power module; maintenance is largely preventative and electrical.

Quality & Certifications

• CE compliant for industrial environments (EMC and safety)
• UL/CSA recognized components (typical for Foxboro modules)
• RoHS compliance for hazardous substances (where applicable)
• Manufacturer’s standard warranty applies; our supplied units include a 365-day warranty

Supporting Components & Typical Pairings

• Foxboro compact baseplates for FBM/Compact I/O (redundant-ready)
