LR/S 2.16.1 ABB i-bus KNX Light Controller 2-Fold 1-10V 16 A MDRC Constant Illumination Module

Product Overview

The ABB i-bus KNX LR/S 2.16.1 is a two-fold light controller designed for modular DIN-rail mounting (MDRC). This advanced device switches and dims two independent groups of luminaires equipped with electronic ballasts and 1-10 V control inputs.

The integrated constant light control function enables continuous comparison of measured room brightness with setpoint values, automatically readjusting the 1-10 V output to maintain consistent illuminance as daylight conditions change.
