Model:I-7514U

Description

RS-485 Active Hub
The I-7514U is a 4-ch RS485 active star wiring hub, it has 4 independent RS-485 output channels and one RS-485 input channel. Each output channel is equipped with an individual driver. The data from a master to the input channel will simultaneously be forwarded to all the four output channels.

Baud Rate Setting
The I-7514U provides 2 modes of baud rate setting, one is Self-Tuner mode and the other is fixed baud rate mode. The Self-Tuner mode can support Multiple Baud Rates and Multiple Data Formats. The Self-Tuner design is exactly the same as used in the I-7513 and I-7510 series.

The Fixed baud rate mode offers a better quality for data transmission over long or lossy lines or electrically noisy environments. 

RS-485 Short-Circuit
The Short-circuit protection can automatically shut off and isolate the faulty channel to ensure continued communication on the other channels.

Termination resistors
In some critical environments, you may need to add termination resistors to prevent the reflection of serial signals.
The I-7514U includes a jumper-selectable 120 ohm termination resistor for each channel (Default = disabled).

LED Indicators
The I-7514U has 6 LED's to indicate the power status and network traffic.
The TxD/RxD LED will flash when the unit is being transmitting or receiving data.

Features

  • True RS-485 Star Wiring Hub
  • Independent RS-485 driver for each channel

  • Hubs can be daisy chained for 256 channels
  • 120[ termination resistor for each channel
  • Power Input, +10 ~ +30 VDC
  • Operating Temperatures, -25 °C ~ +75 °C
  • DIN-Rail mounting
