HMS's CAN repeaters enable coupling of two or more CAN network segments, provide galvanic isolation, and eliminate the effects of EMI (Electromagnetic Interference).The CAN repeaters enable machine builders and system integrators to use extended CAN topologies including tree or star topologies. Furthermore, the integrated galvanic isolation provides a built-in protection against over voltage and the anti-noise circuit of the units eliminates the effects of EMI. IXXAT repeaters are especially designed for use in industrial environments, meeting high demands for robustness, temperature ranges and safety.
How it works
With the use of a repeater, it is possible to build independent electric segments that can be optimally terminated in terms of signals. The repeater substantially increases system reliability, partly because it increases the signal quality, and partly because it makes it possible to isolate malfunctions – keeping the remaining CAN-system fully operational. Furthermore, the implemented monitoring function detects CAN lines which are disturbed or malfunctioning. These lines are disconnected automatically, thus allowing the remaining network to continue functioning normally. After the fault has been eliminated, the disconnected segment is automatically reconnected to the network.
