Overview

The Honeywell MC-TLPA02 Power Adapter is a compact and reliable module engineered for use within Honeywell’s Distributed Control System (DCS) architecture. It converts a wide input voltage range (85–265 VAC) into a stable 24V DC output, powering low-level multiplexer modules and signal interface components such as LLMux, SDI, and SI boards.

Moreover, its robust design and global certifications (CE, TUV, UL508, CSA) make it suitable for deployment in regulated industrial sectors. In addition, the module’s compact footprint and lightweight construction simplify installation in control cabinets and backplanes.

This adapter is widely used in process industries including oil & gas, chemical manufacturing, and power generation, where uninterrupted power delivery to I/O and signal processing modules is essential. Therefore, it plays a critical role in maintaining system uptime and signal integrity.

Technical Data

Typical Applications

• Signal Interface Power Supply: Delivers regulated power to SDI and SI modules for analog/digital signal processing.

• Low-Level Multiplexer Support: Powers LLMux modules used for thermocouple and low-voltage sensor integration.

• Distributed Control Systems (DCS): Ensures stable operation of Honeywell’s control architecture in industrial automation.

• Cabinet Integration: Compact size allows easy installation in control panels and backplane assemblies.

• Process Safety Systems: Supports reliable power delivery to modules involved in safety-critical operations.

For instance, in a chemical plant’s control room, this module powers SDI boards that interface with field sensors, ensuring uninterrupted signal acquisition. In addition, its wide input voltage range allows deployment across global facilities with varying power standards.
