The GA-200 is a multi-function device. 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.
Display: Display the measured analog input, AI1 (or BACnet MS/TP AI1), on the LCD with user defined units of measure
