A new modular and compact solution is now available in order to expand the on-board I/Os of the controller. It’s based on industrial fieldbus. Its architecture avoids the use of the power supply modules and end modules, making the wiring compact and simple, reducing costs and storage management. The system consists of a CPU module and the following additional modules:
- 16DI to add 16 digital inputs, 24V PNP
- 16DO to add 16 digital outputs, 24V PNP - 0.5 A protected
- 8DIO to add 8 inputs + 8 outputs with the same characteristics shown above
Each CPU, which can support up to 6 additional modules, can be connected to the controller by CANopen or, in the near future, by EtherCAT. On request the CPU can be supplied with 2 analog inputs that can be connected to potentiometers or to transducers with 0-10Vdc outputs.
