Implementing Advanced Circuit Protection Technologies for RS-485 Ports
RS-485 Port Interface Requirements
Displayed in Table 1 are the interface specifications for RS-485 ports. Key electrical parameters
of -7 V to +12 V operating voltage with 32 Mbps data transfer at distances of 1200 m are
included. A fully compliant RS-485 port must meet IEC 61000-4-2 (ESD), IEC 61000-4-4
(EFT) and IEC 61000-4-5 (Surge) standards.
Every serial port design depends on the recommended voltage range for the bus pins. RS-485
defines how much protection the device has beyond the −7 V to +12 V. If the environment
demands that bus survives up to ±24 V then external protection must be added or adapted
to meet compliance standards. Bourns offers different circuit protection technologies for
overcurrent and overvoltage protection. The selection of a device or combination of devices
depends on the requirements of the application and specifications of other devices such as the
serial bus driver.
