TDC 3000 NIM Modem 51304511-200 Honeywell CE Network Card

Product Description

The 51304511-200 (Alternate Part Number AC02W36-L0481) is a high-reliability Network Interface Module (NIM) Modem card engineered specifically for the Honeywell TDC 3000 Distributed Control System (DCS). This version is the CE-compliant iteration of the standard NIM modem, designed for use in regulated environments that require strict adherence to European electromagnetic compatibility and safety standards. As the primary paddleboard within the NIM assembly, it provides the physical connection interface for the Universal Control Network (UCN) through dedicated A and B redundant cable ports.

A key advantage of the 51304511-200 is its integrated hardware design. In modernizing the NIM architecture, this single board successfully replaces the combined functions of the legacy PNM, PNM I/O, PNI I/O, and the complex mini-coaxial interconnects used in older configurations. This consolidation significantly improves signal stability across the UCN bus and reduces the potential for hardware-related communication failures. It is a critical component for maintaining the bridge between the Local Control Network (LCN) and UCN-connected controllers such as Process Managers (PM), APMs, and High Performance Process Managers (HPM).

Application & Redundancy Strategy

The 51304511-200 is primarily deployed in mission-critical petrochemical and industrial processing fields where DCS uptime is non-negotiable. By facilitating the redundant UCN link, it ensures that even if one network cable is compromised, the NIM continues to provide the operator station with real-time data from the field controllers. For facilities transitioning to more rigorous compliance standards, upgrading from the non-CE 51304511-100 to this 51304511-200 variant ensures the network interface meets modern regulatory requirements without requiring a complete system overhaul.

Frequently Asked Questions

What is the main difference between the 51304511-200 and 51304511-100?The 51304511-200 is the CE-compliant version, featuring upgraded shielding or components to meet European regulatory standards. Functionally, they both serve as NIM modems, but they are chosen based on the regional compliance needs of the plant.

Can this card replace the older mini-coax cable configurations?Yes. The 51304511-200 is specifically designed to eliminate the need for the older, multi-component PNI/PNM and mini-coax setup, providing a cleaner and more reliable connection point for the UCN cables.
