Electronic Brake Controllers

The Brake Manager

Brake controllers form the interface between the HANNING & KAHL braking system and the vehicle controller. The hydraulic power units, and thus the braking force, are activated in line with the project-specific braking matrix. The brake controllers of type HEY und HEY-C deployed by HANNING & KAHL are found in light rail vehicles, trams and driverless metro vehicles. 

The controllers can implement certain functions with SIL2 in accordance with EN 50657 / EN 50128 (software) and EN 50129 (hardware), and also comply with standard rail-application norms EN 50155, EN 50121-3-2 and EN 61373.
With its very compact design, the brake controller of type HEY-C can also be easily integrated into small spaces, regardless of installation position. The electric interface with various analogue and digital inputs and outputs is sufficiently dimensioned for most applications. Thanks to its modular construction, the brake controller of type HEY offers a higher number of inputs and outputs. This means that very extensive interfaces can be realised. Special functions, for example wheel-slide protection or communication of vehicle speed, can be implemented via the software.
To extend connectivity, both control types can be equipped with different bus systems (CAN, MVB and Ethernet). Software download and extensive diagnosis are usually effected via Ethernet or CAN.

The VSS valve control stage and the NSE control electronics are designed for less demanding tasks in braking management. They activate the brake in analogue/single-channel manner per microprocessor. The PM (electronic semi-conductor contactor) component can switch on/off DC motors with a power up to 1KW wear-free.
