The Interbus open ring topology allow 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.
Plain copper conductors 0.22mm², PE insulation, cores twisted into pairs, pairs bunched and polyester taped, copper wire braid, PVC sheath on static cables and a PUR sheath on dynamic cables.
