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

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.
