Elemaster Group Electronic Technologies
Your ideal EMS partner of innovation
The SIL4 machine point controller represents a significant breakthrough in rail speed management by providing high safety and accuracy for train operations. Designed to meet the SIL4 standard, this advanced system not only improves operational efficiency but also contributes to safer and more sustainable rail transportation.
Machine point controller overview
Developed by Eletech, Elemaster's international design center manager, this machine point controller (also known as an analog speed pointer) enables precise speed control of rail vehicles. Using a rotary encoder, it allows train drivers to set and validate the desired speed via a confirmation button on the train's driver's desk. This approach simplifies daily operations and minimizes the risk of error, greatly improving overall safety.
Key features and operation
The Point Machine controller operates with two electronic boards housed in a robust metal casing and powered by a 110V system battery. The speed setting signal is transmitted as a 4-20 mA current signal, ensuring clear and accurate communication with the train speed management system.
