Thiết bị ổn định đường truyền RS-485 ICP DAS SG-785 CR
Feature
• Switch selectable pull-high/pull-low resistors
• 15-step switch selectable termination resistor
• LED Indicator for Power/Termination
• DIN-Rail mountable
Introduction
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.
Application
RS-485 signal pull-high/pull-low and long distance communication termination resistor setting.
