The 3 channel Dimmer Module is designed to interface variable lighting with bus KNX/EIB and allow dimming of incandescent and halogen loads of 230V, BT and TBT. The product can control 1, 2 or 3 (C1, C2, C3) independent lighting circuits. The outputs number depends on switch 7 position. Device is intended to be installed on DIN rail. The device configuration for commissioning in terms of physical address, group addresses and parameters is done with ETS (Engineering Tool Software) through a download of the Application Program.
