ModBUS Logic Controller
The KET-PLC-200 suitable for the management of domotics scenarios and for refrigeration and air conditioning applications.
It has a considerable number of inputs and outputs that allow for a flexible, modular and expandable network of control devices.
The KET-PLC-200 has two RS485 communication ports, ModBUS master or slave, which allow it to be integrated with the other devices of the X-Monitor network.
The installation is foreseen on DIN rail, in a control panel.
