* Preferably with screening at the negative of a single power supply unit (particularly in the presence of inductive loads such as
motors or neon lamps).
DIGITAL AND ANALOGUE MODULES
Modules with inputs and outputs can be divided into two macrofamilies:
- digital modules: have inputs which read an open or closed status (ON/OFF or 1/0) and outputs which control
an on or off status (ON/OFF);
- analogue modules: have inputs which read a scale of values (from 0 to 255) in 0-10 V voltage or in 4-20 mA current, such as
temperature sensors for example, and outputs which assume a variable value from 0 to 10 V (e.g. light dimmer adjustment).
Another difference between the various modules is the container:
- flush-mounting modules: generally used to collect status information for buttons/switches and send it over the bus; they also
have
low-power outputs for checking local indicator lights or controlling local external relays;
- DIN rail modules: have relay power outputs for controlling electrical loads even at 230 Vac (lights, automations, etc.);
they also have on-board inputs which are the same as those on flush-mounting modules.
Finally, DIN rail modules differ in terms of relay power (6A or 16A) and due to the fact that the 6A modules use relays with
NO (normally open) contact and a common every 4 outputs, while 16A modules use voltage-free changeover contacts
(each with its own common).
MODULE IDENTIFICATION
The first thing that should be done is to assign a serial number other than the default "1" to each module using the SimpleProg
configuration software, which is available to download free of charge from the website pro.comelitgroup.com
• The bus cannot be connected to several modules with the same serial number.
• We do not recommend using serial number “1” in system configuration, so that you can always add an new module later
on, as explained in the chapter relating to configuration software.
