Honeywell TC-PRR021 51309288-225 Experion LS I/O Redundancy Module

The Honeywell TC-PRR021 (part number 51309288-225) is a double-slot control processor redundancy module belonging to the Experion Chassis Series-A platform. Designed for high-reliability industrial automation applications, this redundancy module works alongside C200/C200E control processors within Experion LS systems to provide seamless controller redundancy, enabling fully fault-tolerant dual-chassis control configurations without interrupting process execution.

Features

• Control Processor Redundancy Support: Engineered specifically to support redundant C200 control processor system configurations across identical dual-chassis setups.
• Double-Slot Form Factor: Occupies two physical slot positions within standard Chassis Series-A frames.
• Hot-Swappable (RIUP): Supports Removal and Insertion Under Power in ordinary, non-hazardous locations for minimal disruption during system maintenance.
• Conformal Coating Option: Available as non-conformal coated (TC-PRR021) or conformally coated (TK-PRR021) for enhanced protection in harsh industrial environments.

Applications

• DCS and SIS control systems in continuous process industries
• Redundant C200/C200E control processor chassis architectures
• Experion LS automation platforms requiring high availability and fault tolerance

Technical Specifications

Installation Guidelines

• Chassis Slot Alignment: Insert the double-wide module into two adjacent chassis slot positions within the C200/C200E control processor chassis.
• Redundant Configuration: When implementing C200/C200E in a redundant configuration, ensure two identical chassis are populated with matching modules in identical physical slot locations. Note that no standard I/O modules can be inserted into the redundant C200 control chassis.
• Removal and Insertion Under Power (RIUP): Module insertion and removal under power is permitted in ordinary, non-hazardous locations. RIUP is NOT permitted when equipment is installed in Class I, Division 2 hazardous locations without a hot work permit.
• Cooling & Spacing: Maintain a minimum chassis-to-cabinet vertical distance of 15.2 cm (6.0 in.) and horizontal distance of 10.2 cm (4.0 in.) to ensure adequate ventilation.
