ABB ABZ/S 2.1 KNX Application Unit Time MDRC

Description

Introduction

The ABB ABZ/S 2.1 (Product ID 2CDG110072R0011) is a specialized 1-channel Modular DIN-Rail Component (MDRC) designed for time-dependent execution of switching routines in KNX (TP) bus systems. Functioning as a central time application unit within a building control network, it delivers systematic schedule management across daily, weekly, and annual operational profiles without relying on battery backup or manual onboard controls. This device is part of our KNX automation components range.

This system component supports up to 800 switching events organized across 15 daily routines and accommodates up to 100 special days for custom calendar management. Beyond individual time switching, the ABZ/S 2.1 can trigger actions across up to 300 participants organized into 30 macro groups using single bus commands, while allowing parameter modifications directly via free PZM software without opening ETS.
