Railway Electronics
Our electronic controllers for Railway applications are all designed, and thoroughly tested, in conformity
with the tough requirements of EN 50155 (Railway Applications: Electronic Equipment used on rolling stock).
C-Sigma is an independent supplier of Electronic Brake Controllers for Railway Pneumatic and Electro-Hydraulic Brake Equipments.
At C-Sigma we strongly believe that constant innovation is the key to success.
We therefore take special pride in our patented technique for the detection of defects in wheels, bearings, tracks.
By a proprietary processing of jitter on speed signals, suitable plots are generated to highlight such defects.
Controllers for Electro-Hydraulic Brakes
Successfully operating on Bombardier Niederflur-Beiwagen tram vehicles, in the towns of Rostock and Leipzig (Germany).
It controls and monitors the brake equipment, implementing also the ABS control function.
Controllers for UIC541-05 Brake Equipments
For conventional pneumatic brake equipments the International Union of Railways (UIC) specifies strict requirements to be fulfilled by any
Wheel Slip Prevention Equipment (fiche UIC 541-05).
In particular, UIC 541-05 prescribes the use of independent watchdogs,
one for each controlled axles, and which shall inhibit any override of the Main Brake Command issued by the driver,
would such an override lasts for longer than 10 seconds. This is the purpose of the UIC Watchdog Board, utilised in our controllers
configured for Pneumatic Brake Equipments conforming to UIC prescriptions.
Ubi_Loc GPS/GSM-GPRS Rx & Tx Board
Our rugged GPS Location Rx & Tx Board, with on-board GSM-GPRS modem.
Optional plug-in for our Brake Controllers, it allows customers to add useful functionalities, such as fleet management and remote diagnostics.
It also features a CAN bus interface, allowing the monitoring of dozens of CAN sensors.
