DEUTA REDBOX^® Safe+

The Safety Module

Safety up to SIL 4

The Safe+ module handles safety functions for safety integrity levels up to SIL 4 and expands the safety-related scope of application of the DEUTA REDBOX^® family. The dual-channel fail-safe structure forms the basis of the Safe+ module’s functional and technical safety.

The Safe+ module’s design allows for a high degree of flexibility in configuration, parameterisation and application, e.g. as a time-time or distance-distance safety relay. The Safe+ module can be used independently as a ‘stand-alone’ REDsafe unit or combined with REDBOX 2K recorders. Thanks to its versatile hardware structure, the Safe+ module integrates easily into a wide variety of vehicle architectures.

The Safe+ module has been developed in accordance with standards EN 50126, EN 50128, EN 50129 and EN 50155, and controls the following functions:

Safety travel circuit (SiFa)
Standstill detection / Cold Movement Detection
Rollback protection
Maximum speed monitoring
Speed limit monitoring
Speed signals
Braking curve monitoring
SIL control functions

DEUTA REDBOX® 2K safe+

REDBOX 2K safe+ combines a REDBOX 2K recorder with a safe+ module. The benefits of the REDBOX 2K and the security of the safe+ functions are available in a compact rack-mount unit.

Safe+ Safety Applications

Safety Driving Circuit – SiFa
The SiFa function of the Safe+ module brings the traction unit to a halt by applying emergency braking if the driver becomes incapacitated whilst the train is in motion:

Monitors the speed limit and maximum speed
Prevents the train from rolling away unintentionally
Detects when the train has come to a standstill
Provides the speed

Cold Movement Detection

DEUTA Cold Movement Detection is an integrated safety feature of the DEUTA REDBOX^® recorder that utilizes the existing speed sensors and requires no additional sensors. Because CMD is integrated into the REDBOX, no additional device is required.

Brake curve monitoring

The REDsafe EBS (Emergency Brake Supervision) system monitors the intensity of an emergency braking manoeuvre. To do this, two axle-mounted incremental encoders transmit the wheel speed via two redundant channels.

SIL control function

The safety-related applications of the REDsafe module, in conjunction with the SSCU, are designed to provide additional SIL control functions.

The safety-related data from the REDsafe module can, for example, be used as a safe source for additional safe speed monitoring.
