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
