CANbus remote I/O adapter

The Unitronics EX-RC1 remote I/O adapter allows multiple adapters to connect to a single programmable logic controller, with up to eight standard expansion modules to each adapter via CANbus.

By expanding distributed control capabilities and I/O support to a maximum of 512 points, the EX-RC1 allows Unitronics Vision PLCs to be used in larger machines and systems, such as conveyors, paper handling and printing. Using the EX-RC1, the Vision units can now be placed at a convenient operator stand; and it allows I/Os to be distributed in different locations on the machine with a single CANbus cable running between the units. Through the CANbus network, a distance of up to 1000 m can be achieved. For maximum system flexibility, it is also possible to connect several PLCs and several expansion adapters on one CANbus network.

To simplify the development of the main control application on the PLC, this unit enables the creation of local basic logic relevant to the I/Os that are attached to it.

When connected to digital I/Os only, it will automatically recognise the modules that are attached to it and no further configuration is required. Configuration is only required for analog I/O.
