• Status LEDs: Power, Run, Active, Fault (card edge for diagnostics)

• Debug Port: On‑board serial port for firmware upgrade & troubleshooting

Core Functions

• Centralized Control Processing: Executes core control logic, data acquisition, and loop control for TDC3000 nodes

• LCN Communication Management: Manages data exchange between controllers, workstations, and I/O modules

• System Diagnostics & Redundancy: Supports fault detection, hot‑swap, and redundant operation for high availability

• Real‑Time Data Processing: Handles process data, alarms, and historical logging with low latency

• Configuration & Download: Stores and executes system configuration downloaded from GUS/US workstations

Application Scope

• Honeywell TDC3000/TPS DCS (process control nodes, controller cabinets)

• Process industries: power generation, oil & gas, refining, chemical, petrochemical, pharmaceutical

• Critical control loops requiring high reliability and real‑time performance

• Replacement/upgrade of legacy TDC3000 system controller cards

Operation & Maintenance Instructions

• Install in dedicated controller slot of TDC3000 cabinet backplane

• Ensure proper LCN network connection before power‑on

• Verify “Run” and “Active” LEDs are lit during normal operation

• Keep ambient temp < 55 °C; avoid dust, moisture, and vibration

• Replace only with Honeywell‑certified 51197018‑100 controller cards
