Its hot-swappable architecture and predictive diagnostics minimize downtime while maximizing operational continuity in environments where every second of availability counts.

Built for process industries demanding 99.99% uptime, the WH1-2FF addresses the critical challenge of power redundancy without sacrificing rack space or thermal efficiency. Plant operators benefit from automatic failover protection that activates within milliseconds during AC mains disturbances, while maintenance teams appreciate the field-replaceable design that eliminates costly emergency shutdowns. With universal 100-240 VAC input and conformal-coated circuitry, this module adapts to global voltage standards and harsh industrial atmospheres.

Whether you're upgrading legacy control cabinets or designing new DCS installations, the 1X00024H01 delivers proven reliability backed by Emerson's 20+ year spare parts commitment and ISO 9001 manufacturing standards. Reduce unplanned outages, extend equipment lifespan, and maintain regulatory compliance with a power solution trusted by Fortune 500 energy producers worldwide.

Core Features & Business Value

→ Active-Active Load Sharing: Proprietary current-balancing algorithms distribute electrical load evenly across both power modules, preventing thermal hotspots and extending component lifespan by 40-50% compared to traditional primary-backup configurations.

✓ Seamless Hot-Swap Capability: Replace failed modules during full operation without process interruption—technicians can service one supply while the redundant unit maintains 100% system power, eliminating six-figure shutdown costs in continuous manufacturing.

→ Universal Global Input: Automatic voltage detection across 100-240 VAC eliminates region-specific inventory—deploy identical modules in North American 110V facilities and European 220V plants, reducing spare parts complexity by 50%.

✓ Predictive Health Monitoring: Built-in diagnostics track output ripple, thermal rise, and efficiency degradation to identify aging capacitors 3-4 weeks before failure, enabling scheduled replacements during planned maintenance windows rather than emergency callouts.

→ Industrial-Hardened Construction: Conformal-coated PCBs withstand moisture, dust, and chemical vapors in non-climate-controlled equipment rooms, while 3000 VAC isolation protects sensitive control circuits from ground faults and electrical noise.

✓ Comprehensive Safety Certifications: UL508, CE, CSA, and FM approvals ensure compliance with North American and European industrial standards, streamlining project approvals and insurance requirements for multinational installations.

Typical Application Scenarios

Utility-Scale Power Generation: In combined-cycle gas turbines and coal-fired boiler systems, the 1X00024H01 powers Ovation controllers managing combustion optimization, emissions monitoring, and grid synchronization. A single power interruption can trigger turbine trips costing $500K-$2M in lost generation and restart expenses—redundant supplies prevent these cascading failures while maintaining NOx compliance during load transitions.

Petrochemical Refining Operations: Distillation columns, catalytic crackers, and product blending systems rely on continuous I/O rack power for temperature control loops and safety instrumented systems. The WH1-2FF's 20ms holdup time bridges momentary AC sags during motor starts, while its hot-swap design allows maintenance during 24/7 production runs without initiating emergency shutdown sequences.

Municipal Water Treatment: SCADA networks controlling pump stations, chemical dosing, and UV disinfection require uninterrupted power to meet EPA Safe Drinking Water Act mandates. Redundant supplies ensure regulatory compliance during utility brownouts, while predictive diagnostics reduce after-hours emergency service calls by 60% through scheduled component replacement.

Pharmaceutical Manufacturing: Clean room HVAC controls and batch reactor systems demand validated power sources with full traceability. Factory test certificates and serial number tracking satisfy FDA 21 CFR Part 11 requirements, while dual-output architecture supports critical process control and non-critical monitoring circuits from a single module.

Data Center Infrastructure: Building management systems monitoring cooling, fire suppression, and access control benefit from the module's -20°C to +70°C operating range and >88% efficiency, which reduces HVAC loads in equipment rooms by 12-15% compared to linear power supplies generating excess heat.

Technical Parameters & Selection Guide

Selection Criteria: Calculate total DC load by summing all I/O module current draws plus 20% safety margin. For systems requiring >10A, deploy the WH1-2FF redundant configuration. Verify ambient temperature does not exceed 50°C without forced ventilation—each 10°C rise above this threshold reduces available output current by 25%. In applications with frequent AC disturbances, confirm upstream circuit breakers provide 30A minimum rating to handle inrush current during simultaneous module startup.

Extended Functions

Remote Monitoring Integration: Dry contact alarm outputs interface with SCADA systems and building management platforms, enabling centralized power status visualization across distributed control cabinets. Integrate with Modbus RTU or Ethernet/IP networks for real-time voltage, current, and temperature telemetry.

Parallel Expansion Capability: Connect multiple WH1-2FF modules in parallel to achieve 30A, 40A, or higher current capacity for large I/O racks—built-in current-sharing ensures balanced load distribution without external diode-OR circuits or custom wiring harnesses.

Customization Options: Factory-configurable output voltages (12 VDC, 48 VDC) available for OEM integrators requiring non-standard DCS architectures. Conformal coating upgrades (MIL-STD-810 tropical environments) and extended temperature variants (-40°C to +85°C) support offshore platforms and arctic installations.

Frequently Asked Questions

Q: How does the 1X00024H01 integrate with existing Ovation DCS cabinets?
A: The module mounts on standard 35mm DIN rail and connects via screw terminals accepting 12-22 AWG wire. It replaces legacy single-output supplies without cabinet modifications—simply parallel the DC outputs to your existing distribution terminal blocks. Consult the installation guide for proper grounding and wire routing to minimize electrical noise coupling.

Q: What current capacity do I need for a typical Ovation I/O rack?
A: A fully populated 16-slot I/O rack typically draws 6-8A depending on module types (analog inputs consume 150-200mA each, while relay outputs draw 300-400mA). Add 20% safety margin, so the WH1-2FF's 20A combined capacity supports 2-3 racks. For larger systems, parallel additional modules or upgrade to higher-capacity models.

Q: Can this power supply reduce energy costs in my control room?
A: Yes—the >88% efficiency rating converts 12-15% less AC power to waste heat compared to older linear supplies, reducing HVAC cooling loads. In a typical 10-rack installation, this translates to 400-600W heat reduction, saving $300-$500 annually in cooling costs at $0.12/kWh industrial rates.

Q: What installation requirements ensure optimal performance?
A: Mount vertically with terminals facing down to prevent dust accumulation. Maintain 50mm clearance on both sides for convection cooling—forced ventilation required if ambient exceeds 50°C. Use twisted-pair wiring for DC outputs to minimize EMI, and bond the chassis ground to cabinet earth via 14 AWG minimum conductor.

Q: Does the module support remote monitoring and diagnostics?
A: Standard models provide LED status indicators and dry contact alarm outputs for AC fail, DC fail, and overload conditions. Optional communication modules enable Modbus RTU or Ethernet/IP integration for real-time voltage, current, and temperature data accessible via SCADA or building management systems.

Q: How do I verify compatibility with international voltage standards?
A: The universal 100-240 VAC input automatically detects and adapts to local mains voltage—no jumpers or switches required. Verify your facility's voltage falls within ±10% of nominal (90-264 VAC accepted range) and frequency is 47-63 Hz. CE marking confirms compliance with European Low Voltage Directive for 230V installations.
