Description
Introduction
The ABB TSA/K24.2 (Product ID: 2CDG120050R0011) is a 24 V AC/DC thermoelectric valve drive engineered for the precise opening and closing of valves within heating, ventilating, and air-conditioning (HVAC) systems. Designed in a normally closed (NC) operating state and enclosed in an IP54 splash-water-protected housing, this device delivers reliable thermal regulation for individual room climate control in KNX system topologies. This device is part of our professional KNX Actuators range.

Engineered for seamless installation, the TSA/K24.2 connects via a pluggable cable and utilizes quick snap-on mounting onto standard valves through compatible VA/Z valve adapters. It is designed to operate under the control of ABB Electronic Switch Actuators ES/S or Electronic Relays ER/U paired with Universal Interfaces US/U and room thermostats, providing an efficient valve drive mechanism for commercial and residential automation projects.
