Honeywell MC-TLPA02 51309204-175 Power Adapter Module
The Honeywell MC-TLPA02 (part number 51309204-175) is a power adapter module engineered for Honeywell Distributed Control System (DCS) architectures, including TDC3000 and Experion PKS platforms. It converts a wide AC input voltage range of 85–265 VAC into a regulated 24 VDC output, delivering up to 25 A to power low-level multiplexer (LLMux) modules, Serial Device Interface (SDI) boards, and Serial Interface (SI) components.
Power Conversion and Module Integration
Designed for installation within DCS control cabinets and backplane assemblies, the adapter conditions incoming AC mains power to supply stable DC operating voltage for sensitive signal processing hardware. By providing direct power to LLMux assemblies and serial interface modules, it maintains reliable voltage regulation for thermocouple data acquisition and field sensor signal routing across automated control networks.
