Link 3 TCMS architecture.

High Speed PWM outputs for Motor Control and Traction

As a key TCMS player in the railway industry for several decades, LEROY AUTOMATION highlights its product range with customizable pulse-width modulation(PMW) features.
The main technical features are:         
Up to 6 PWM outputs at a frequency up to 1KHz
Configurable PWM frequency and duty cycle with a resolution respectively of 1Hz and 1% 
Flexibility for "H-bridge"circuitry implementation and cabling.

PWM outputs can easily be configured as standard outputs of the BRIO remote I/O module product line based on solid-state discrete outputs.
Typical applications include: HVAC subsystems, door control systems, lavatory automation, traction powerpacks and various DC motor applications.


LEROY AUTOMATION has been awarded a major contract by SIEMENS
to supply the Vehicle Control and Monitoring System (VCMS) architecture
for their newest generation of automated passenger transportation platforms.

The CityVal trains are supervised
by a Communication-Based Train Control (CBTC) driverless system,
and LEROY AUTOMATION will provide the heart and brains of the VCMS architecture.
The scope of supply includes on-board train control units,
remote I/O modules and train monitoring system recorders
