Serial Converters/Repeaters/Isolators (310)

Reliable Serial Communication
Choose serial converters, repeaters and isolators by interface, port count, baud rate, isolation, connector type, DIN rail format, driver support and cable distance

DistriNode serial converters, repeaters and isolators help connect legacy devices, PLCs, meters, POS terminals, access control, CNC equipment, routers, servers and industrial controllers where RS-232, RS-422, RS-485, USB or Ethernet links must stay stable. Compare USB-to-serial adapters, multi-port converters, repeaters for longer cable runs, opto-isolated interfaces, surge protection, screw terminals, DB9 connectors, DIN rail housings, Windows and Linux drivers, Modbus use, half-duplex or full-duplex wiring and whether the link is for commissioning, permanent automation, service laptops or electrically noisy environments.

How to Choose Serial Converters

Match the standard
RS-232, RS-422 and RS-485 use different wiring, distance and signalling rules.
Check isolation
Optical isolation protects equipment when ground loops or industrial noise are possible.
Plan drivers
Service laptops, servers and embedded systems may need specific chipset support.
Respect distance
Repeaters and proper termination help long RS-485 runs stay reliable.

Integration tip: Write down the serial standard, connector, baud rate and wiring mode before replacing a converter.

Frequently Asked Questions

Can RS-232 and RS-485 be connected directly?
No. They need a proper converter because signalling and wiring are different.
When is isolation needed?
Use isolation when devices are powered from different sources or the environment has electrical noise.
Why do some USB serial adapters fail with old devices?
Chipset drivers, voltage levels and handshake lines may not match the equipment.
