RS-422/485 Isolator Repeater Converter Features • Wide range of input voltage and power protection • Polarity guard that prevents damage from reverse power connection and over voltage protection • Rugged metal casing with better mechanical and EMI protection • Provides CMR‐10KV/µs optical isolation between the two RS-422/485 ports and 1KV/µs isolation between the DC power and both RS-422/485 ports • Can also act as the converters from RS-422 to RS-485, 4-wire RS-485 to 2-wire RS-485 • Clear LED indications of power status, RS-422/485 data signal status (TX/RX) and operation modes (RS-422/485 4W or RS-485 2W) • Clear indications of all signals on the casing allow easy and proper connection • Push high/pull low resistors for RS-422/485 • Plug-in screw terminal blocks for easy RS-422/485 and power supply wiring • DIP switch settings for RS-485 2-wire with ERADC auto mode, RS-422/485 4-wire mode • DIP switch setting for internal terminal resistors • 15KV ESD surge protection • External power supply • 35mm DIN rail installation kit • FCC, CE, RoHS approved Side View Company Website www.bluskyelectronics.com Back View In digital communication systems, a repeater is a device that receives a digital signal on an electromagnetic or optical transmission medium and regenerates the signal along the next leg of the medium. In electromagnetic media, repeaters overcome the attenuation caused by free-space electromagnetic-field divergence or cable loss. A series of repeaters make possible to extend the signal over a longer distance. In real application where the environment is tough, isolations become a necessity between the two digital ports and between the digital ports and the power supply. BSC3122i is the repeater and isolator designed for the above purposes. Furthermore, BSC3122i is also the converter to convert the RS-485 2 wired signals to RS-485 4 wired signals or vice versa. BSC3122i also provides the repeater and converter functions where isolations are not necessary. Product Website www.convertermodem.net
