ABB 23OK24 Fibre optic coupler Serial communications

Description:

The fiber optic coupler 23OK24 is suitable for the RTU560. the module is used to transmit data via 2 independent optical links (receive and transmit).

Fiber optic cables are insensitive to inductive and capacitive interference as well as to potential differences between the two data communication devices.

In critical environments or when potential isolation is required, fiber optic cables can be used to bridge across distances. With 200 μm fiber optic cables, the maximum distance is up to 2600 meters.

The module can be used to convert the receive and transmit data signals of the following electrical interface standards to fiber optic signals:

- RTU560 SPB I/O bus
- RS-485 bus
- RS-232 C

The fiber optic coupler 23OK24 can be connected to the RTU500 series coupler 560FOC40. the RTU520 I/O adapter 520ADD03 R0002 and the RTU511 I/O adapter 23AD64 R0002.
