ABB AC/S1.1.1 Application Controller, Basic, MDRC (2CDG110205R0011)

Description

Introduction

The ABB AC/S1.1.1 Application Controller (Product ID: 2CDG110205R0011) is a Modular DIN-Rail Component (MDRC) designed for holistic Heating, Ventilation, and Air Conditioning (HVAC) automation across KNX (TP) bus systems. Engineered to assist system integrators and consultants in achieving strict building energy performance objectives like EN 15232 and LEED, this basic automation controller bridges central HVAC infrastructure with dedicated room-level automation. This device is part of our KNX AC Controller range.

Operating on a 24 V DC auxiliary voltage with a power loss rating of 3 W, the AC/S1.1.1 integrates pre-defined automation modules alongside a graphical logic editor for custom control strategies. System engineering is executed entirely within the Engineering Tool Software (ETS), eliminating the necessity for additional external software tools, while offering an automatically generated web-based user interface for real-time KNX system management and monitoring.

Key Features

• Compatible with KNX (TP) bus systems in a Modular DIN-Rail Component (MDRC) housing.
