6-5. Analog Output Interface (Option 03 : 4~20mA Output)
This Option card converts weight value to Analog Electric Current output(4~20mA) and transfers to
external devices(Recorder, P.L.C), controlled by electric current output.
6-5-1. Specification
① Output Current : 4~20mA (Output Range : 2~22mA)
② Accuracy : More than 1/1,000
③ Temperature Co-efficiency : 0.01%℃
④ Max Loaded Impedance : Max 500Ω
※ When Weight display is “Zero”, 4mA current will be output, when Weight display is “Full Capacity”,
20mA current will be output.
6-5-2. Circuit
※ “LO” terminal is not a “GND”, so this “LO” terminal
do not be connected with other “GND” terminal on other
devices.
6-5-3. Output Adjustment
① This output is adjusted as when the weight is “Zero”, output is “4mA” and When the weight is “Full
capacity”, output is “20mA”.
② If you need additional adjustment, please adjust with “VR1(Zero)”, “VR2(Span) on the Analog Output PCB.
※ Remark
This Analog option card converts Displayed weight value(Micro-process data) to analog value on D/A
Converter(Digital to Analog converter)
This D/A Converter has Max 1/4,000 accuracy, so this output is not suitable for high accuracy application, like
more than 1/3,000.
6-5-4. Connecter (9pin, “D-type” female)
