Bourns Solutions: Circuit Protection
Application Note: Implementing Advanced Circuit Protection Technologies for RS-485 Ports
RS-485-based industrial systems must be capable of operating in very noisy and harsh electrical environments. Reliable circuit protection is a crucial to avoid damage and overload of the system. This application note describes a robust three-stage solution for RS-485 serial device ports. Learn how to apply the combination of Bourns Transient Blocking Unit (TBU®), gas discharge tube (GDT) and transient voltage suppression (TVS) products to meet industry standards and implement highly effective protection against power cross, ESD, EFT and surge pulses.
