Interbus Cables
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.
3 Pair Interbus cable
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.
