Features:
- Supports two nodes on the Local Control Network (LCN) via coaxial cable, effectively expanding the system’s capacity
- Engineered specifically to replace older KLCN boards and be compatible with TDC 3000 and Experion PKS systems
- Features robust protection including short-circuit tolerance, surge absorption, and electrical isolation to ensure high durability in the field
The 51305072-600 is distinguished by its role in the LCN (Local Control Network) as a "Dual Node" interface . In a Honeywell DCS, the LCN is the high-speed data highway that connects various components (consoles, historians, controllers). To add more I/O points, you must add a node, and the 51305072-600 does exactly that. It allows two distinct node addresses to be added to the network. However, user configuration is required; the module features a physical "jumper pack" that technicians must set to define the specific node number.
For plants running legacy Honeywell TDC 3000 systems, the 51305072-600 is a lifeline. It is designed as a direct replacement for the discontinued KLCN-CB board, allowing engineers to maintain operational I/O racks without a costly full-system DCS upgrade . It also acts as the CE-compliant version of the older board (CLCN A/B) for users in regulated markets.
The 51304072-600 is built to survive harsh industrial environments, which is why it is often preferred for critical infrastructure. It adheres to strict industrial EMC (Electromagnetic Compatibility) standards, meaning it resists interference from heavy motors, VFDs, and high-voltage switchgear found in refineries and steel mills . The module features a high-density, multi-layer PCB housed in a dust-proof chassis, suitable for IP20-rated cabinets . It also maintains signal integrity over long distances via its coax interfac.
The 51305072-600 Honeywell I/O Board may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Oil & Gas: Monitoring distillation towers and cracking units in oil refineries, ensuring the main control station can acquire real-time data from thousands of pressure and temperature points.
- Large Power Plants: Ensuring precise information exchange between turbine and boiler control units in coal-fired or nuclear power plants.
- Chemicals & Pharmaceuticals: Providing a highly reliable data backbone for batch control, ensuring traceability of the production process.
- System Expansion: Increasing I/O capacity in dual-node racks and supporting LCN network node address configuration.
- Operating Temperature: Typically operates stably between -20°C and +55°C.
- Storage Temperature: Withstands environments ranging from -40°C to +85°C.
- Electromagnetic Compatibility: Although this model (-600) is a non-CE version, it still features multi-stage filtering and electromagnetic shielding technology to ensure undistorted signal in noisy industrial environments.
- Redundant Communication Control: Dedicated to communication for Cable B. It, along with the module responsible for Cable A (such as 51305072-500 or -200), forms a redundant network. When one cable fails, the system can seamlessly switch to prevent control interruption.
- Node Diagnostic Indication: Onboard LED indicators provide real-time diagnostics of power, communication status, and link health, helping maintenance personnel quickly isolate faults within 10 minutes.
- Hot-Swappable: Supports online replacement, allowing maintenance without stopping the entire system.
- Address characterization: The module is equipped with an address pack, which must be configured according to its specific node location in the LCN network to ensure the accuracy of the control network path.
