Protection Of Communication Systems From Electrical Disturbances


It also provides necessary immunity to a system against electrical noise interferences and differential ground

Sparr Electronics, a company involved in the design, development and manufacturing of electronics and communications products presents the RS485/422 isolator/repeater that provides complete isolation between communication devices so that they are protected against any inadvertent damage due to electrical disturbances. The ISO 485/422 also provides necessary immunity to a system against electrical noise interferences and differential ground. The product can also be used for extending the operational distance by acting as a serial repeater / amplifier. 

The converter is populated with surface mount components for good reliability and size reduction. At the same time, it is equipped with good and reliable isolation to data signals.
