Remote I/O adapter

The Unitronics EX-RC1 remote I/O adapter allows multiple adapters to connect to a single PLC, 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 device allows PLCs to be used in larger machines and systems, such as conveyors, paper handling and printing, and 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.

To simplify the development of the main control application on the PLC, this ‘smart’ 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, the unit will automatically recognise the modules that are attached to it, with no further configuration required.
