Overview of the solution and functionalities
CAN-IO is IO Remote module for the management of remo-te
inputs and outputs, which can be completely customised to
suit customer requirements, adapting perfectly to the machine
or system to control.
Thanks to its exibility and ease of use, CAN-IO can be used in
a variety of sectors and for numerous process and automation
process controls, such as:
• the wood industry (gluing, etc.);
• packaging (packing, labelling, etc.);
• food industry (pasteurisers, etc.);
• chemical industry (autoclaves, etc.);
• metal working (washing, etc.);
• plastic working (dryers, coolers, etc.).

The remote input and output module (I/O) allows:
• acquisition of multiple information for the appliances
controlled and from the environment, via signals and
sensors;
• control and regulate appliances through dierent types of
signals and commands.
The modules are available in dierent models and can manage
up to a total of 40 channels (inputs and outputs) each, with
the following limits type (see ordering codes):
• digital inputs: 24 max;
• fast digital inputs (meters): 6 max;
• digital outputs: 16 max in total (outputs 0.5 A: 16 max;
• outputs 2 A: 16 max; relay outputs: 8 max);
• PWM outputs: 8 max;
• Temperature inputs (thermocouples, thermo resistance
PT100, thermo resistance PT1000): 10 max in total;
• analogue inputs (power input ±10 V, current input 0/4…20
mA, extensometer input, potentiometer input): 8 max in
total;
• analogue outputs (power outputs ±10 V, current outputs
0/4…20 mA): 8 max in total.
The main characteristic of the module is that it is assembled
according to user requirements, combining dierent type
inputs and outputs on the same card, in the quantities
required. In this way they adapt perfectly to the requirements
of the machine or system to be controlled.
The modules can be prepared for assembly on DIN runner or
plate, according to requirements.
