RS-485 pull-high/pull-low and Termination Resistors Module

The SG-785 is an optional module that is used to improve the communication of RS-485 network. It provides switch selectable pull-high and pull-low resistors on RS-485 network. It also has 15-step switch selectable termination resistor such that the user can select a proper termination resistor to be connected to the RS-485 network easily.

Features:

  • Switch selectable pull-high/pull-low resistors
  • 15-step switch selectable termination resistor
  • LED Indicator for Power/ Termination
  • DIN-Rail mountable

Applications:

RS-485 signal pull-high/pull-low and long distance communication termination resistor setting.
