ABB KNX Blind Actuator 12-fold 230V, Travel Detection

ABB KNX Blind Actuator 12-fold 230V, Travel Detection

The JRA/S12.230.5.2 is part of ABB’s current JRA/S blind and roller-shutter actuator range. It sits on the DIN rail in the distribution board, takes its logic power from the KNX bus and switches 12 230 V AC motor outputs. Each channel handles up and down travel with the interlock and changeover delay built in, so the motor is protected without extra wiring.

What it does

• 12 independent blind/shutter channels — drives 12 motors, or 6 motors with separate up/down groups where the project needs it.
• 230 V AC motor supply, DIN-rail mounted (MDRC), powered from the KNX bus for its logic.
• Manual operation on the front — every channel can be driven by hand during commissioning or a bus failure, with no ETS download needed.
• Travel detection — the actuator measures actual travel time, so slat and height positions stay accurate over the life of the installation.
• Blind, roller shutter, awning, louvre and vertical blind modes, plus slat adjustment, scene recall, sun protection, wind and rain alarms and forced operation.
• Genuine ABB, supplied by Infinitex in Dubai with trade pricing, ETS product data and UAE-wide delivery.

Where it fits

A 12-channel unit suits a large villa, hotel floor or office block. Because the KNX side is entirely software-defined, the same hardware covers blinds, roller shutters, awnings and louvre systems — you change the operating mode in ETS rather than the device.
