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.
