Woodward PCM128-HD OEM ECU ECM Engine Computer Module

Woodward PCM128-HD OEM ECU ECM Engine Computer Module

Description 

The Woodward PCM128-HD is a dual-fuel locomotive control module specifically designed for Cummins India dual-fuel locomotives. It serves as a key control unit for managing the mixed control of fuel and gas, regulating operating parameters, and monitoring system status of dual-fuel locomotives, ensuring their stable and efficient operation.

This module must be used in conjunction with the Woodward ToolKit service tool, which is available in two versions: ToolKit Professional and the standard ToolKit. ToolKit Professional is a licensed software tool that allows application engineers to modify or create new screens for service configuration, configure control software to meet specific site or application requirements, monitor and tune system variables selected in the GAP application program, trend variables, and upload and download all tunable and configuration variables from the control. The standard ToolKit, on the other hand, lacks the screen modification capability but offers the same functionality as ToolKit Professional otherwise.

Communication between the PCM128-HD and a PC can be established via an RS-485 communication interface, which requires the use of an RS-485-to-RS-232 converter (such as B&B Electronics Model 485SD9TB, Woodward P/N 1784-1038) or an RS-485-to-USB converter (such as B&B Electronics Model USOTL4, Woodward P/N 1784-1037). When connecting, the SCL+ line of the PCM128-HD (corresponding to pin J1 B22) is connected to the TD (B) pin of the converter, and the SCL– line (corresponding to pin J1 B23) is connected to the TD (A) pin of the converter.
