Model Explanation

• 51196727: Base part number for Honeywell TDC3000 dual‑node processor module

• ‑100: Standard revision (original factory spec, no enhanced features)

Technical Parameters

• Device Type: Redundant dual‑node processor / controller

• Compatibility: Honeywell TDC3000 / TPS Distributed Control System

• Processor: High‑speed 32‑bit industrial CPU (dual core for redundancy)

• Memory: On‑board RAM + non‑volatile flash for program/data storage

• Redundancy: 1:1 dual‑node hot standby (automatic failover < 500 ms)

• Communication: TDC3000 LCN (Local Control Network) interface

• Operating Temp: 0 °C to +60 °C

• Humidity: 5%–95%, non‑condensing

• Dimensions (W×H×D): Approx. 483 mm × 260 mm × 80 mm (19” rack‑mountable)

• Weight: Approx. 12.5 kg

• Certifications: CE, UL, CSA, ATEX (for hazardous areas)

• Lifespan: Designed for 24/7 industrial operation (MTBF > 100,000 hours)

Interface & Communication Configuration

• Network Port: LCN (Local Control Network) – connects to TDC3000 control network

• Redundancy Port: Internal high‑speed link for dual‑node synchronization

• Status LEDs: Power, Run, Fault, Sync, LCN Activity (front panel)

• Expansion Slots: Optional I/O or communication expansion (system‑dependent)

Core Functions

• Redundant Process Control: Dual‑node architecture ensures zero downtime during node failure

• Real‑Time Data Processing: Executes control loops, logic, and data acquisition for plant operations

• LCN Network Management: Communicates with other TDC3000 nodes (GUS, controllers, I/O)

• Hot Standby Failover: Automatic switch to standby node with no process interruption

• System Diagnostics: Built‑in self‑test and fault reporting for easy maintenance

Application Scope

• Honeywell TDC3000 / TPS DCS control systems (core controller node)

• Critical process industries: power generation, oil & gas, refining, chemical, petrochemical

• Plants requiring high availability (99.999% uptime) and redundant control

• 19” rack‑mounted control rooms with TDC3000 LCN infrastructure

Operation & Maintenance Instructions

• Install in standard 19” industrial rack; ensure proper ventilation (front/rear airflow)

• Connect LCN cable and redundant sync cable before powering on

• Check front‑panel LEDs: “Run” solid = normal operation; “Fault” blinking = diagnostic needed

• Keep ambient temperature < 60 °C; avoid direct heat or moisture

• Replace only with Honeywell‑certified 51196727‑100 modules for full redundancy compatibility
