Description

Introduction

The ABB BE/S4.20.3.2 is a KNX System Component for detecting independent input signals from floating contacts. It scans these contacts using an internally generated scanning voltage and displays the state of the input via yellow LEDs.

ABB BE/S4.20.3.2

For B2B KNX projects, this model should be specified and ordered by its exact ABB model and SKU, BE/S4.20.3.2, to avoid substitution errors. The device is powered via the ABB i-bus® and does not require an additional power supply, and it supports KNX Data Secure.
