Installation & Operation Manual
OUTPUT OPTION CARD
If the Series 3000 Flow Monitor was ordered with the Output Option card, it will have several additional outputs.
1. Analog Output ( 0-20mA; or 4-20mA ) which can be converted externally to 0-5VDC, 1-5VDC with a 250 Ohm resistor; or
0-10VDC or 2-10VDC with a500 Ohm resistor. A 15VDC power supply is provided to permit current sinking or sourcing. The
Series 3000 has special software that permits the Analog output.
2. USB for direct access to a computer using a standard mini-USB cable.
3. RS-485 for fully addressable Modbus or BACnet communication.
