Description
The ABB 1KGT011800R5001 23OK24 is a fibre optic coupler designed for the ABB RTU560 Remote Terminal Unit platform. It provides optical transmission through two independent glass-fibre links for receive and transmit data. The module supports optical isolation of the RTU560 I/O bus and can also be used for RS-485 and RS-232 communication applications. It is suitable for communication environments where electrical isolation and resistance to inductive or capacitive interference are required. The 23OK24 uses BFOC/2.5 bayonet fibre connections and operates with an 820 nm optical wavelength.
The module can be applied in RTU communication networks, substation automation systems and other industrial communication installations using compatible ABB RTU560 hardware. Its optical interface can help bridge communication equipment across electrically different potentials while maintaining the required data connection.
