Turck FOC series fieldbus optocouplers
Turck’s FOC series optocouplers are designed for transmitting fieldbus communication via fibre-optic cable. The single- or dual-channel devices of the FOC series transfer fieldbus protocols such as Profibus-DP or Modbus RTU as light signals along fibre-optic cables. The zone 1 IECEx variant of the FOC couplers can be installed in Zone 1 and can transmit intrinsically safe signals in accordance with RS485IS.
The FOC media converters can cover large distances, more than 2500 m, depending on the fibre-optic cable used. Optical cables are also immune to electromagnetic interference. Users can also configure ring topologies for maximum availability with the devices in addition to point-to-point connections. All devices are provided with a universal shielding concept that can be easily adapted to individual processes. An integrated alarm output of the FOC converters also shortens the time required for troubleshooting.
