32 Channel RS485 Isolator

32 Channel RS485 Isolator

Benefits

  • Protects downstream equipment against electrostatic discharge events (ESD) and against upstream faults with at least 2 kV isolation
  • Prevents ground loop signal level errors common in long distance serial links that affect signal integrity
  • Safely increases link distance without compromising quality and reliability

Features

  • Isolated bidirectional 4-wire or 2- wire data link up to 1.5 Mb/s rates
  • Isolated grounds between input and output
  • Up to 1.2 km distance (4000 ft) depending on data rates
  • Differential receivers for electrical noise tolerance
  • Switchable 120 ohm terminations to reduce bit error signal echoes
  • 19” rack-mountable enclosure
  • Lightweight 5052-H32 aluminum alloy enclosure
  • IEC-60320-C14 fused inlet with cord retaining clip to prevent unintentional disconnects
  • Redundant power supplies with external LED health indicators
  • 85-264 VAC 47-63 Hz wide power input range
