6-4. 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.
6-4-1. 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.
6-4-2. Circuit
※ “LO” terminal is not a “GND”, so this “LO” terminal
do not be connected with other “GND” terminal on other
devices.
6-4-3. 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.
