industrial isolated Converter
485LDRC9
The 485LDRC9 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 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.
The 485LDRC9 is ideal for critical industrial communications, factory
automation, in-cabinet conversion, warehouse automation, security, and
many other applications.
• Extend data up to 1.2 km (4,000 ft.)
• 2 kV optical isolation on input/output
• Wide operating temperature (-40 to +80 °C)
• Modbus compatible
• UL Recognized, NEMA TS2
• Automatic Send Data Control
