SKU: BMFBR. Category: .

Features

  • ADFC (Automatic Data Flow Control), uses a technique protected by US patent #5,729,547 that automatically senses and controls the direction of RS-485 data eliminating the need for software control.
  • 3-in-1 signal conversion converts RS-232 or RS-422 or RS-485 to fiber optic signals. This conversion automatically senses RS-422 four wire operation.
  • Status LEDs are provided for power, transmit data, receive data, optical collision and link detect signals. These are handy for verifying operation and troubleshooting network problems.
  • Transient voltage protection, all electrical signal and power inputs are protected against high voltages.
  • Baud rate independent, no switches or jumpers to set. Automatically adapts to all standard and non-standard baud rates up to 115Kbaud.
  • Versatile power supply, The unit can be powered by a wide range of AC or DC voltages. Wall plug adapters are available from duTec or others. A pluggable screw terminal is also provided for use with other power supplies. 7 to 24 volts AC or 9 to 36 volts DC @ 90 mA max.
  • Pluggable terminal blocks, industrial rated terminal blocks for ease of installation or removal. Accepts up to 16 AWG wire.
  • Standard 820 nm operation uses standard ST connectors and readily available 50/125 or 62.5/125, 100/140, or or 200 um HSC multimode fiber.
  • 650 nm plastic fiber version for popular lower cost plastic fiber, over shorter distances.
  • DIN rail mounting accessories available for easy wiring.
