Features:

  • UCN protocol communication through 75 Ω coaxial BNC interface
  • Dual-channel redundant transmission supporting A/B network paths
  • Configurable node addressing with revision-controlled hardware structure
The Honeywell 51304511-100 is designed as a communication interface board within NIM-based control systems, enabling structured data exchange through the UCN protocol. It uses a BNC connector interface and operates over coaxial transmission media to support stable network communication. The module integrates into the system architecture as a paddle board installed within the NIM frame, ensuring consistent positioning and electrical connection. Its design allows it to function as a dedicated communication layer between system nodes.

Within system configuration, the Honeywell 51304511-100 supports dual-channel communication to maintain redundancy across UCN A and B paths. Address configuration is managed through SW2 using binary-weighted logic with odd parity requirements, while SW1 preserves revision identification for hardware traceability. This structure ensures controlled identification and network addressing consistency within the system environment. The board maintains defined electrical behavior through backplane-powered operation.

The Honeywell 51304511-100 operates at a transmission rate of 5 Mbps over 75 Ω coaxial cables such as RG-6 or RG-11. Power is supplied through the NIM backplane using typical 5V or 12V DC logic levels, while maintaining low power consumption below 5 W. These characteristics support stable operation within modular system frameworks. The design ensures compatibility with existing NIM architecture without requiring external power modules.In system evolution, the Honeywell 51304511-100 standard version is complemented by the 51304511-200 CE-compliant version. Both maintain similar structural roles within the NIM communication framework while supporting regulatory and system-level requirements. The module continues to function as a core interface element for UCN-based communication systems.

The 51304511-100 Honeywell NIM Modem I/O Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Honeywell 51304511-100 NIM Modem I/O board is designed for UCN protocol communication using a BNC connector interface. It operates with a transmission rate of 5 Mbps over 75 Ω coaxial cable such as RG-6 or RG-11, ensuring structured signal transmission within the network architecture.

The Honeywell 51304511-100 supports dual-channel redundancy through A/B communication paths. It is powered via the NIM backplane with typical logic-level supply of 5V or 12V DC, and maintains a power consumption of less than 5 W, ensuring low internal load within the system.

In configuration, the Honeywell 51304511-100 includes SW1 for revision pinning of the NIM Modem board, which is fixed and only updated when the board revision changes. SW2 is used for UCN node address setting in test mode, requiring binary-weighted configuration with odd parity, where the primary NIM address must be an odd number.

The Honeywell 51304511-100 is installed as a paddle board within the NIM frame and must remain within the designated module structure for operation. It supports CE-compliant configuration through the 51304511-200 version, while maintaining compatibility with standard NIM Modem system architecture.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does the board use dual-channel communication?
Dual-channel A/B communication provides redundancy to maintain stable network operation. In Honeywell 51304511-100, both channels support continuous UCN protocol transmission.
How is the communication address configured on the board?
The UCN node address is set through SW2 using binary-weighted switches with odd parity requirements. The Honeywell 51304511-100 uses this configuration only in test mode or system identification.
What is the function of SW1 on the module?
SW1 stores the revision pinning of the board and reflects hardware version identification. It is fixed and only changed when the Honeywell 51304511-100 hardware is updated.
