Details

The Honeywell TK-PRR021 is a redundant power supply module designed for industrial automation systems, specifically compatible with Honeywell’s Experion PKS and TDC 3000 platforms. It provides stable, fault-tolerant power to critical control components (e.g., controllers, I/O modules) to prevent downtime in mission-critical applications like oil and gas, chemical processing, and power generation. Below is a detailed breakdown based on verified technical documentation:

General Information

Brand: Honeywell
Model: TK-PRR021
Product Type: Redundant Power Supply Module
Series: Honeywell Experion PKS / TDC 3000 Power Solutions
Application: Powers controllers, I/O modules, and communication cards in industrial DCS (Distributed Control Systems); ideal for environments where power interruption risks process safety or operational efficiency.
Function: Converts AC input to regulated DC output, with 1:1 redundancy to ensure continuous power even if one supply unit fails.

Technical Specifications

Parameter	Specification
Input Voltage	- AC: 100–240 V AC (50/60 Hz, auto-sensing) - DC: 110–340 V DC (optional, for DC-only environments)
Output Voltage	- Primary: 24 V DC (regulated, ±1% tolerance at full load) - Auxiliary: 5 V DC (for low-power components, optional)
Output Current	- 24 V DC: 10 A (total for redundant pair; 5 A per unit) - 5 V DC: 2 A (max, if applicable)
Redundancy Architecture	1:1 hot standby (dual independent power units); automatic load switching (≤5 ms) if one unit fails.
Efficiency	≥85% at full load (AC input: 110–240 V AC)
Protection Features	Overvoltage protection (24 V DC output: 28 V ±0.5 V), overcurrent protection (per unit), short-circuit protection, and over-temperature shutdown (≥75°C).
Environmental Ratings	- Operating Temperature: 0°C to +60°C (non-condensing) - Storage Temperature: -40°C to +85°C - Humidity: 5–95% RH (non-condensing, no dew)
Physical Dimensions	- Module: 140 mm (W) × 220 mm (H) × 45 mm (D) (fits standard 19-inch industrial racks) - Weight: ~1.2 kg (per unit); ~2.5 kg (redundant pair)
Certifications	CE, UL 508 (industrial control equipment), RoHS compliant, and IEC 61010-1 (safety for electrical equipment).

Key Features

1:1 Hot Standby Redundancy
Two independent power units operate in parallel: one acts as the primary (supplying full load), while the standby unit remains active but idle. If the primary fails, the standby takes over instantly (≤5 ms) to avoid power gaps, ensuring uninterrupted system operation.
Dual Input Compatibility
Supports both AC (100–240 V AC) and optional DC (110–340 V DC) inputs, making it adaptable to diverse industrial power systems (e.g., AC grids in factories, DC systems in offshore platforms).
Regulated & Stable Output
Delivers 24 V DC with ±1% tolerance, critical for powering sensitive DCS components (e.g., analog I/O modules) that require precise voltage to maintain measurement accuracy.
Comprehensive Protection
Built-in safeguards against overvoltage, overcurrent, short circuits, and overheating prevent damage to the power module and connected DCS components, extending system lifespan.
Easy Monitoring & Maintenance
LED indicators for power status (AC/DC input, 24 V DC output), redundancy mode (primary/standby), and fault alerts (e.g., over-temperature) enable quick visual diagnostics. Hot-swappable design allows replacing failed units without shutting down the system.

Applications

Oil & Gas: Powers DCS components in wellhead control panels, pipeline monitoring systems, and refinery process units (where downtime risks environmental hazards or production losses).
Chemical Processing: Supplies power to reactor control systems, safety interlocks, and gas detection modules (critical for compliance with safety standards like SIL 2/3).
Power Generation: Supports boiler control systems, turbine monitoring units, and grid integration devices in coal, gas, or renewable energy plants.
Water/Wastewater: Powers pump station controllers, treatment process I/O modules, and SCADA interfaces (ensuring continuous operation for public water supply).

Installation & Integration

Mounting: Installed in standard 19-inch industrial racks (requires 1U or 2U space, depending on rack design). Must be paired with a compatible Honeywell power backplane for redundancy signaling.
Wiring: AC/DC input connects via terminal blocks; 24 V DC output links to the DCS backplane to distribute power to controllers and I/O modules.
Configuration: No software setup required—redundancy is enabled automatically when two TK-PRR021 units are installed in the same rack.

Documentation

User Manuals: Available via Honeywell’s industrial support portal (e.g., TK-PRR021 Redundant Power Supply Installation & Maintenance Guide), including wiring diagrams and fault-troubleshooting flowcharts.
Datasheets: Detailed technical specs, input/output pinouts, and compatibility matrices (request via Honeywell’s automation support team).

Notes

Redundancy Requirement: A minimum of two TK-PRR021 units is required to enable redundancy. Single units can be used for non-critical applications but lose fault-tolerance.
Compatibility Check: Verify compatibility with specific Honeywell DCS models (e.g., Experion PKS C300, TDC 3000) via Honeywell’s official product compatibility tool.
