6-3. Analogue Output Interface. (4~20mA :
Factory default set value
)
This output card converts weight value to Analog output signal (4~20mA) and transfers to
external devices(Recorder, P.L.C), controlled by voltage output.
6-3-1. Specification
Output Current
4~20㎃ (Output Range :2~22㎃)
Accuracy
More than 1/1,000
Temperature Coefficient
0.01%℃
. Max. Loaded Impedance
500Ω MAX.
According to display weight of indicator, analogue signal will be output.
The operator can determine 20mA output spot by setting F51 function.
Under Calibration mode or “CELL-ERR” condition, Analogue output will not activated.
If the output is deactivated, the last output signal value will be hold until next activation.
6-4-2. 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”.. (F51-00 setting)
② The Analogue value is already adjusted from factory with DIGITAL MULTI-METER
③ 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.
※ If you want to change the analogue output, Please set the Jumper pin like a following
picture.
