ART. 20004820
Module 20004820 is equipped with a 0-10V / 4-20m analogue input, a 0-10V output and a digital input. The
analogue input may be used for connection of analogue sensors, such as light sensors for indoor/outdoor use,
level sensors, wind sensors, etc. The 0-10V output can be used for connection of LED lights, fluorescent lights
or other devices equipped with a 0-10V input. The module is equipped with a digital input, freely programmable
via the programming software, for the connection of normal pushbuttons and switches or for the connection of
sensors with voltage-free contacts (e.g. presence sensors).

PROGRAMMING
SimpleProg software is required to program Comelit home automation devices; this software can be
downloaded from the website pro.comelitgroup.com. Programming must be carried out by connecting the
device to the BUS and sending the programming over this.
ADDRESSING
The address of the module on the Comelit home automation BUS must be set using the DIP-switches on the
module itself, see table on page 8.
• If the DIP-switches are altered, the power supply must be cut off and reactivated for the new address
to be set on the module.
• The module address cannot be changed via SimpleProg.
