The 485LDRC9 is an optically isolated RS-232 to RS-422/485 converter. RS-232 Signals interface through a convenient DB9F connector or through a terminal block. RS-422/485 signals and the power inputs connect to the terminal block. Built in send data control circuitry eliminates the need for external software to control handshake signals. Optically Isolated data lines, with 500W surge suppression, ensures that the connected equipment is protected even in the harshests environments. The converter operates on externally sourced 10 to 30 VDC power. The enclosure has a DIN rail mount that is designed to fit easily on a standard 35mm rail. The 495LDRC9 is ideal for your ctritical industrial communications needs.
Wide temperature and power ranges make B&B Electronics serial
converters ideal for your harsh duty applications. Automatic Send Data
Control, Modbus compatible. The RS-232 side has both a
terminal block and a DB9 female connector; the RS-485 side has a terminal
block. Requires external power supply not included.
