GreenAlert GA Series
GA-200
Display, Alarm and Analog to RS-485 BACnet/Modbus Bridge

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 the output of any analog sensor

Read a BACnet MS/TP AI object in lieu of the physical analog input without a BAS network

Analog input range 0-10 VDC or 4-20 mA

16-character alpha-numeric LCD

Define and display user defined input with custom units of measure

Buit-in high, low or high/low setpoint alarm with user defined tolerance and delay

Automatic or manual alarm reset

Active alarm is displayed on LCD, illuminates a red LED and closes a N.O. dry contact relay

Convert the analog input to a BACnet MS/TP AI, AO or AV object or dual register Modbus value

Make any analog sensor a network sensor

Simple pushbutton interface does not require any proprietary hardware or software
