Diesel Engine Controls

    We have designed and installed one-off systems to meet the individual needs of a particular plant arrangement. In addition, we can supply cost-effective standalone controllers, pre-programmed that are configured by the end user to meet the requirements of the application, such as the TC41-DG Governor System.

    TC41-DG Governor System

    Affordable alternative to full control system retrofit

    • Easy to install
    • Increased reliability
    • Programmable and configurable

    The TC41 microprocessor system is designed to meet the requirements of Diesel GOVERNING.

    The processor, I/O modules, ¼ VGA screen and keypad are housed in a 3U high 19" rack subassembly a wide range of input and output modules provides interface with plant devices and options for alternative or additional functionality. Obsolete and unreliable equipment is replaced with modern digital electronics having high reliability and accuracy and is an affordable alternative to a full control system retrofit. Communication facilities provide interface with other diagnostic and control equipment.
