galvanically isolated one another
- the phase supplying the device is the same supplying all
the devices making the network.

1 INTRODUCTION
1.1 Introduction
c-pro 3 NODE kilo is a range of programmable controllers for applications in refrigeration and air conditioning sectors.
The controllers have a considerable number of inputs and outputs; they allow to realize a flexible, modular and expandable
control devices network.
The variety of available communication ports (RS-485, CAN, USB and Ethernet) and supported communication protocols
make easier the integration of the devices in systems.
The application software can be realized through the UNI-PRO 3 development environment for programmable controllers.
