The iRCS (integrated Retarder Control System) is an electronic box designed by Telma that integrates both the control and power functions into a single module.

The innovative electronic design of the iRCS's power function significantly reduces the retarder's energy consumption and preserves its electric circuits.

The RCM (Retarder Control Module) is an electronic box designed by Telma. As it is compatible with CANBUS networks, it ensures seamless integration of Telma retarders into all vehicles equipped with any electronic braking system (ABS, ESP, EBS, speed control, automatic transmission control...).

A CB (Contactor Box) ensures power supply switching through the retarder's various power stages.

The CB's design makes it a simple, effective and proven solution.

The LSC (Low-Speed Cutoff) prevents the retarder from being unnecessarily fed when the vehicle is stopped, thus preserving electric systems of the vehicle as well as of the retarder.

A Lever allows the driver to directly control the retarder. It also allows activation of the speed control function on downhill slopes.

The various models of Telma Levers allow for smooth integration into any dashboard configuration.

Integrated into the vehicle's pneumatic air brakes system, the pressure switch controls the automatic and progressive activation of the retarder through the brake pedal.
