ABB KNX Blind Actuator 4-fold 230V, Travel Detection

ABB KNX Blind Actuator 4-fold 230V, Travel Detection

The ABB KNX Blind Actuator JRA/S4.230.5.2 belongs to 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 4 230 V AC motor outputs. In addition, each channel handles up and down travel with the interlock and changeover delay built in, so the motor stays protected without extra wiring.

What it does

• 4 independent blind/shutter channels — drives 4 motors, or 2 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 this ABB KNX Blind Actuator fits

A 4-channel unit suits a villa floor or a small office. Because you define the KNX side entirely in software, the same hardware covers blinds, roller shutters, awnings and louvre systems. So you simply change the operating mode in ETS, rather than the device.
