Output Option Card
OUTPUT OPTION CARD
If the Series 3000 flow monitor was ordered with the Output Option card, it will have these additional outputs:
•
Analog Output (0...20 mA; or 4...20 mA), which can be converted externally to 0...5V DC, 1...5V DC with a 250 Ohm
resistor, or 0...10V DC or 2...10V DC with a 500 Ohm resistor . A 15V DC power supply is provided to permit current sinking
or sourcing . The Series 3000 flow monitor has special software that permits the analog output .
•
USB for direct access to a computer using a standard mini-USB cable .
•
RS485 for fully addressable Modbus or BACnet communication .
USB Port
To communicate using the USB port requires Windows® HyperTerminal or other similar communications software . This port is
part of the Analog Output Option card . See
