ARIO 500

Modular remote I/O system

ARIO 500 is a compact and modular remote I/O system, composed by fieldbus couplers, power modules and I/O modules.


To improve interchangeability and maintenance, the I/O modules are composed by two separable parts: the mechanical part, including a jagged clamp (that allows tidy wiring), the communication bus contacts, the power contacts and the hooking system for the 35mm DIN rail, and the electronic I/O part.


Mounting and maintenance The installation is immediate and doesn’t imply the use of specific tools. Every module include the mechanical DIN rail fastening by means of a lever lock and can be replaced without removing the adjoining ones.


Thanks to the ‘slide&plug’ mechanism, it is possible to replace the electronic part without removing the mechanical one, nor its wiring («Permanent Wiring»).
The electrical connection diagram of the module is printed on the side of the electronic part.

Signalling

Every module includes status signalling LEDs for the single I/O and diagnistic LEDs.

I/O identification

To identify every single I/O, removable and customizable tags are inserted on each module.

Fieldbus coupler

The coupler manages the communication with the control system via the fieldbus and the communication with the single I/O modules via the internal high performance bus. Every coupler is bundled with a power module, that comes physically paired at delivery.

The ARIO 500 system includes two fieldbus couplers, with the following standards:
• EtherCAT
• Modbus TCP

Power modules

The power modules, depending on the quantity and the type of installed modules, integrate the power supplied by the coupler.

I/O modules

Digital modules

The digital modules, with 4 or 8 channels, include input units with rates of response up to 2μs and output units with 0,5A and 2A.

Some of the modules include diagnostic functionalities


Analog modules
Analog modules, with 2 or 4 channels and 16bit resolution, include input and output units for tension or current, and temperature measure units for the most common sensors.
All modules include diagnostic functionalities


Encoder modules
The counter/encoder modules, with 1 or 2 channels, include TTL and HTL incremental encoders and SSI absolute encoders.

System configurability
The couplers can support up to 64 I/O modules. Depending on their configuration it may be necessary to integrate their power supply with the specific additional modules.
The couplers are bundled with a plastic terminal cover to protect the contacts of the last module
