ABB JRA/S4.24.5.2

Description

Introduction

The ABB JRA/S4.24.5.2 is a KNX actuator in the KNX Actuators category for controlling up to 4 independent 24 V DC motors via ABB i-bus® KNX. It is intended for positioning blinds, roller shutters, awnings and other shading products, and for controlling doors, windows and ventilation flaps.

Because the available product data is limited, buyers, consultants and installers should verify the exact ABB model, SKU JRA/S4.24.5.2, and project BOQ requirements against the official ABB product documentation before ordering. This helps avoid substitution errors where similar-looking KNX actuator references may not match the required motor type, control function or project specification.
