Advantech BB-485LDRC

Model BB-485LDRC is an optically isolated RS-232 to RS-422/485 converter. RS-232 signals interface through a terminal block. RS-422/485 signals and power inputs connect to the terminal block. Terminal blocks are arranged to allow easy wiring inside a control panel.

Built-in Automatic Send Data Control circuitry allows quick set-up and eliminates the need for external software drivers to control handshake signals. The converter operates on externally sourced 10-30 VDC power.

Optically isolated data lines (2,000 V on input/output) with 500W surge suppression ensure that connected equipment is protected even in the harshest environments. DIN rail mount design snaps on standard 35mm rail and a small form factor fits neatly into tight cabinets.

Models BB-485LDRC is ideal for critical industrial communications, factory automation, in-cabinet conversion, warehouse automation, security , and many other applications.
