The GA-200 is a multifunction device that displays an alarm and analog to the RS-485 BACnet/Modbus bridge. It can be used to display the output of any analog or BACnet MS/TP sensor. The GA-200 can act as network bridge and convert an analog output sensor to a BACnet MS/TP or Modbus RTU sensor. The device has a built-in high, low or high/low setpoint alarm that can alarm on a physical analog input or BACnet MS/TP AI. The GA-200 can also display the physical analog input or BACnet MS/TP AI on a 16-character LCD with user-defined units of measure.
