Product Overview
The Honeywell 51305508-200 is a high-reliability power distribution module engineered exclusively for Honeywell’s TDC 3000 distributed control system (DCS), serving as a critical component for regulated power delivery to TDC 3000 nodes (e.g., processors, I/O modules, operator stations). Designed to ensure stable and redundant power supply in industrial automation environments, this module converts and distributes primary power (AC or DC) to secondary voltages required by TDC 3000 components, minimizing the risk of system downtime due to power fluctuations or failures.
As an upgraded variant of legacy power modules (e.g., 51305508-100), it incorporates enhanced protection features and CE compliance, making it suitable for deployment in EU countries and global industrial facilities with strict regulatory requirements. It is primarily utilized in high-availability applications such as oil & gas refineries, power generation plants, and chemical processing facilities, where uninterrupted power to control systems is critical for operational safety and efficiency.
The 51305508-200 supports both standalone and redundant configurations, integrating seamlessly with TDC 3000 power monitoring systems to provide real-time status updates and alarm notifications for power anomalies. Its rugged design ensures reliable operation in harsh industrial environments, with robust shielding against electrical noise and environmental stressors.
Key Features
CE Compliance & Regulatory Adherence
Certified to meet EU EMC Directive (89/336/EEC) and Low Voltage Directive (2014/35/EU), marked with the “CE Mark” for legal deployment in EU member states.
Complies with global safety standards, including UL 60950-1 (Information Technology Equipment) and IEC 61508 (Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems), ensuring safe operation in industrial settings.
Redundant Power Distribution
Supports N+1 redundancy when paired with a second 51305508-200 module, enabling automatic failover if the primary unit experiences a fault. This redundancy eliminates single points of failure, critical for maintaining power to TDC 3000 nodes in mission-critical applications.
Load-sharing capability in redundant setups ensures balanced power distribution between modules, extending component lifespan and preventing overload conditions.
Multi-Voltage Output & Conversion
Provides regulated secondary outputs: 5 V DC (±5%), 12 V DC (±10%), and 24 V DC (±5%)—compatible with all TDC 3000 components, including processors (K2LCN/K4LCN), I/O boards (e.g., 51305072-100), and operator stations.
Accepts wide-range primary input: 100–240 V AC (50/60 Hz) or 120–300 V DC, accommodating global power grid variations and simplifying international deployments.
Advanced Protection Mechanisms
Overvoltage/undervoltage protection: Automatically shuts down outputs if voltage exceeds safe thresholds, preventing damage to TDC 3000 components.
Overcurrent protection: Resettable fuses for each output channel limit current to safe levels, protecting against short circuits in downstream wiring.
Thermal shutdown: Activates if internal temperatures exceed 70°C (158°F), preventing module damage due to overheating in enclosed cabinets.
Real-Time Monitoring & Diagnostics
Integrates with TDC 3000 power monitoring systems via a dedicated communication port, transmitting real-time data on input voltage, output current, and module temperature.
LED status indicators for power input, output health, and fault conditions (e.g., overload, overheat) enable quick visual diagnostics during maintenance.
Rugged Industrial Design
Constructed with a metal chassis and conformal-coated PCB to resist moisture, dust, and chemical contaminants, suitable for Class I, Division 2 / Zone 2 hazardous locations when installed in a certified enclosure.
Vibration resistance (2g maximum at 10–2000 Hz) and shock resistance (30g for 11 ms) to withstand mechanical stress in industrial environments.
