Product Overview

The NT255 (Part Number: 00012170-00) is the fundamental power regulation module for the Bachmann M1 automation system. Engineered for installation in Slot 1 of the M1 backplane, it converts a standard external 24 VDC input into the precise, low-noise internal voltages required to drive the processor modules, communication interfaces, and I/O cards. The NT255 (00012170-00) acts as the system's electrical heartbeat, featuring high efficiency and integrated protective circuitry to ensure continuous operation in demanding industrial environments like wind farms and maritime vessels.
