Analog modules are used as integrated I/O on CN expansions, to manage additional inputs and outputs.
Connection between modules is handled on a proprietary serial BUS named BLT (Bus Locale Tecnos).
They can be linked directly to the CN or remoted, using the knuckle-coupler CAN BUS with CANOpen communication protocol (DS301/401).
There are 2 models of analogic input and output modules, some require a separated power supply.
