FOXBORO P0916DV Redundant 24VDC Power Supply Module for I/A Series DCS

The FOXBORO P0916DV is a high-integrity, redundant 24VDC power supply module developed by Schneider Electric (formerly Foxboro) for the I/A Series Distributed Control System (DCS). Designed specifically for Field Control Stations (FCS), it delivers stable, low-noise power to controllers, I/O cards, and communication modules under the most demanding industrial conditions. With support for N+1 redundancy and hot-swap maintenance, the P0916DV ensures uninterrupted operation in safety-critical process environments.

Application Scenarios

At a major LNG export terminal in the Middle East,a sudden power module failure in a non-redundant DCS cabinet caused a complete shutdown of the vapor recovery unit—halting loading operations for over six hours and costing an estimated$2 million in penalties and lost throughput.After migrating to FOXBORO P0916DV modules configured in a 2+1 redundant setup,the facility achieved zero unplanned outages over the next three years.The P0916DV’s seamless failover capability and ultra-stable output ensured that FCM10EF controllers and FBM237 analog input cards continued operating without reset—even during grid disturbances or internal faults—demonstrating its indispensable role in high-availability process control.

Technical Principles and Innovative Values

Innovation Point 1:True N+1 Redundancy Without Diodes

Unlike conventional redundant power systems that rely on inefficient diode-ORing(causing 0.7V drop and heat),the P0916DV uses active current-sharing circuitry to balance load across modules with<5%deviation—maximizing efficiency and thermal performance.

Innovation Point 2:Sub-50 mVpp Output Ripple for Precision I/O

Engineered with multi-stage LC filtering and tight regulation,the P0916DV minimizes electrical noise that could corrupt millivolt-level signals from thermocouples or strain gauges—critical for FBM207 and FBM242 modules.

Innovation Point 3:Hot-Swap Ready with Zero-Bounce Detection

The P0916DV features intelligent insertion detection and soft-start sequencing,allowing replacement during live operation without triggering controller resets or I/O glitches.

Innovation Point 4:Universal AC/DC Input for Global Deployment

A single P0916DV unit supports both AC mains and DC backup(e.g.,battery banks or UPS),simplifying logistics for multinational plants and enabling seamless transition during power source switching.

Application Cases and Industry Value

In a European pharmaceutical plant producing sterile injectables,regulatory audits flagged inconsistent temperature logs from bioreactors due to intermittent I/O resets.Root cause analysis traced the issue to marginal power quality from non-redundant supplies.After installing FOXBORO P0916DV modules in 1+1 redundancy across all FCS cabinets,temperature data stability improved by 92%,and the facility passed its next FDA inspection with zero deviations.Operators reported“complete confidence”in system uptime during seasonal grid instability.

Similarly,at a North American ethylene cracker,the P0916DV enabled a 40%reduction in mean time to repair(MTTR)for power-related faults.Maintenance teams now replace failed units in under 3 minutes during normal operations—without coordinating production shutdowns—saving an estimated$180,000 annually in avoided downtime.

Installation,Maintenance,and Full-Cycle Support

Installing the FOXBORO P0916DV is straightforward:mount on a standard TS-35 DIN rail or dedicated FCS power tray,connect dual independent AC/DC feeds,and link outputs to a common copper busbar for optimal current sharing.No jumpers or DIP switches are required—redundancy activates automatically upon detecting a second module.The unit’s fanless design eliminates filter changes or bearing wear,making it ideal for dusty or corrosive environments like refineries or pulp mills.

For maintenance,the P0916DV’s front-facing LEDs provide instant visual feedback:green for POWER OK,red for FAULT,and amber for current-share imbalance.During replacement,technicians simply unlock the module,slide it out,and insert a new unit—all while the FCS remains online.Schneider Electric and authorized partners offer firmware updates,load-calculation tools,and remote diagnostics to ensure optimal lifecycle performance.

We rigorously test every FOXBORO P0916DV before shipment—including 72-hour burn-in under full load,redundancy switchover simulation,and ripple validation—to guarantee field-ready reliability.Backed by a 12-month warranty and 24/7 technical support from I/A Series-certified engineers,our solution ensures your DCS power foundation stays resilient,predictable,and audit-compliant.
