ARIO 500

Modular remote I/O system

Lifecycle status: Active mature

HIGHLIGHTS

  • Compact and modular remote I/O system 
  • The I/O and power supply modules consist of two physically separable parts: the mechanical part, including a terminal block with stepped contacts, which promotes orderly wiring, communication bus contacts, power supply contacts, and 35mm DIN rail attachment system, and a cartridge-formatted electronic part 
  • Installation is immediate and requires no special tools
  • Each module provides mechanical locking and unlocking with lever fastening and can be replaced without removing adjacent modules 
  • Through the "slide&plug" mechanism, it is also possible to replace the electronics without removing the mechanical part and related wiring ("Permanent Wiring")

Overview

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

Module types

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
