Main Features and Advantages

The ABB TK851 stands out due to its superior features tailored for industrial applications.A key advantage is its complete immunity to electromagnetic interference(EMI).In factories and power plants,motors,variable speed drives,and welding equipment generate significant electrical noise that can corrupt data signals transmitted over copper cables.The TK851 transmits data as pulses of light,making it completely impervious to these disturbances.This ensures a clean and reliable communication link,which is essential for stable control loops.

Another significant feature is its galvanic isolation capability.Since there is no electrical connection between the devices,the ABB TK851 prevents ground loops and voltage differences from causing current flow between connected equipment.This not only protects the hardware from damage but also enhances the safety of the entire system.The cable’s duplex design allows for simultaneous two-way communication,which is crucial for high-speed industrial protocols.Its rugged outer jacket provides excellent protection against mechanical stress,oil,and chemicals,ensuring a long service life in harsh industrial environments.Unlike plastic optical fiber(POF)cables,the glass fiber in the ABB TK851 allows for much longer transmission distances with minimal signal loss,making it ideal for connecting devices over large areas or between buildings.The TK851 is the reliable choice for ensuring a robust and fault-tolerant network connection.

Application Field

The ABB TK851 is an indispensable component in a wide range of industrial applications where robust and secure data communication is essential.It is most commonly used in large-scale factory automation and distributed control systems,connecting controllers,drives,and I/O modules across vast distances.Its immunity to EMI ensures that real-time process data is transmitted without error,which is vital for safety and precision.In power generation plants,the TK851 is used for connecting excitation systems,turbine controllers,and circuit breaker panels,where the high-voltage environment makes optical communication the only safe and reliable choice.It is also widely used in the metal and pulp and paper industries,where heavy machinery and high-power motors are common,creating electrically noisy environments.Its use in these demanding applications is a testament to its reliability and performance.

Installation and Maintenance

Pre-installation preparation:Before installing the ABB TK851,ensure that both the transmitting and receiving devices are powered off.Inspect the cable for any physical damage or kinks.Clean the connectors with an appropriate lint-free cloth or compressed air to ensure optimal signal transmission.The cable should be routed carefully,avoiding sharp bends that could damage the optical fibers.

Maintenance recommendations:The TK851 is a durable product that requires minimal maintenance.The primary maintenance activities involve ensuring the cable is free from physical stress,such as excessive pulling or crushing,and keeping the connectors clean.Periodically inspect the cable for any signs of damage to the outer jacket.If the cable is suspected of being faulty,it should be replaced with a genuine,original part to maintain system integrity.
