Interbus Cable

The Interbus open ring topology allows integration of different field devices from control level down to sensor switches over one system. Unlike traditional ring systems Interbus uses one cable to route data back and forth to all devices. Each device or unit will amplify the signal before sending it on to the next station. The data is transmitted over a 3 pair screened cable.  For remote applications a composite data and power cable is available.
