Description

The RWD 2 Control Centre is designed for setting up a decentralised SHEV system. For this purpose, up to 60 Control Centres can be organised in a monitored bus system with up to nine SHE groups. The decentralised arrangement allows the Control Centres to be placed close to the windows or flaps. As a result, the power cables between the Control Centre and the actuator are significantly shorter, which considerably reduces the costs for the system cabling.

To ensure that the system can still be operated centrally, the SD 2 operating unit is required as an accessory. It is connected either directly to any Control Centre or to a junction box. Via a four-line display and a keypad, it shows the status of the bus system and enables the system to be set and operated.

The RWD 2 is available in two versions: depending on the number and type of actuators, it can provide a total output current of 10 A or 20 A. Select the desired output current in the following drop-down menu.

Please note the approved accumulators for use in our RWA control units and controls.
