3. Product Overview

The 51404170-175 is a heavy-duty power system cage assembly for legacy Honeywell TDC3000 and TPS DCS systems. It serves as the mechanical housing and power distribution backbone for the 51198651-100 power supply module. The integrated backplane routes regulated power to controller and communication boards inside the chassis, and it reserves space for the memory backup battery to preserve configuration data during power outages. The rugged metal frame protects internal power components and ensures stable backplane contact. It is an obsolete critical spare for maintaining legacy DCS control systems in oil & gas, chemical, power and petrochemical plants.
