Logiplus manufactures a range of PWM traction encoders used to control the traction/brake train lines. The EMCO AGC PWM traction-brake encoder has the following functionalities: Emission of the traction and brake efforts set values calculated from the master controller on the PWM train lines, Automatic speed control (VI, cruise control), Coupling up and decoupling (speed regulated at 3 km/h by the PWM encoder), Automatic ‘Deadman’ activation on driver’s activity, Control of Traction /Brake effort indicator and of the automatic speed control indicator. The EMCO+ product initially developed for the SNCF NAT trainset has a safety integrity level of SIL2 and controls the pneumatic brakes. It includes all the functionalities of the EMCO AGC and has an ethernet connection. The EMCO Regio2N product initially developed for the SNCF Regio2N trainset has a safety integrity level of SIL2. It includes all the functionalities of the EMCO AGC and has an ethernet connection.
