(±10%), 0.7 Amps (standard DC power)
100 to 240VAC (±10%/-15%), 50-60Hz, 0.2 Amps (with AC power option)
Note: Fluctuations of AC and DC power supply are not to exceed ±10% of rating.
Class I Equipment (Electrical Grounding Required for Safety).
Installation (Over-voltage) Category II for transient over-voltages.
Inputs/Outputs:
4-20mA Channel 1:
• Standard isolated 4-20mA output congured to indicate ow; fault indication per NAMUR
NE43.
4-20mA Channel 2:
• Standard isolated 4-20mA output congured to indicate either ow or temperature; fault
indication per NAMUR NE43.
Pulse/Alarm:
• Isolated open collector output rated for 5 to 24VDC, 20mA maximum load, 0 to 100Hz (the
pulse output can be congured to either transmit a 0 to 100Hz signal proportional to ow
rate or an on/o alarm).
Remote Switch Input:
• Can be congured to reset the ow totalizer and elapsed time.
Serial Communication
• Isolated Modbus RTU (RS485) option
• Isolated HART communication option
USB Communication:
• Isolated USB 2.0 for interfacing with a laptop or computer is standard.
• FT3 View™: A free PC-based software tool that provides complete conguration, remote
process monitoring, and data logging functions through USB communication.
4-20mA and Loop Verification:
Simulation mode used to align 4-20mA output with the input to customer’s PLC/DCS.
