- Compatibility review covers documented backup execution, receiving hardware and configuration.
51202330-300 is the documented Honeywell memory backup hardware for TDC 2000 and TDC 3000. As the installed backup assembly, it maintains controller memory through a power interruption through controller memory-retention circuit. Its execution is defined by documented backup execution, so signal direction, receiving hardware and configured channel use must agree with the approved system design.
Before replacement, record the installed position, terminal or backplane assignments, connected devices and current configuration status. Match the complete catalog marking, backup assembly, controller memory-retention circuit, documented backup execution, receiving assembly and every printed revision. After installation, restore the approved configuration, check module and system diagnostics, and prove every affected measurement, command or communication path before return to service.
The 51202330-300 Honeywell Memory Backup Hardware may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
