BB-485LDRC9

BB-485LDRC9 is an industrial isolated converter. It is an optically isolated RS-232 to RS-422/485 converter. RS-232 signals interface through a DB9 female connector or a terminal block. RS-422/485 signals and power inputs connect to the terminal block. Terminal block is 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 to 30VDC power. Optically isolated data lines 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. It is ideal for critical industrial communications, factory automation, in-cabinet conversion, warehouse automation, security, and many other applications. cULus Recognized, File Number: E222870, NEMA TS2 approved.
