7-6. ANALOG OUT(4~20㎃)INTERFACE(Option 03)
This Option is to transmit display weight value by Current out to the external devices (such
as Recoder, P.L.C Main Control etc.) controlled by analog signal.
▶ SPECIFICATIONS
Output Current
4~20㎃ for Available Range, Output Range is 2~22㎃
Accuracy Over 1/1000
Temperature Coefficient 0.01%℃
MAX Load Impedance 500Ω MAX.
▶ When weight display is 0, Output current 4㎃ will be made. When weight display is maximum
display capacity, 20㎃ will be made.
▶ This should not connected any other device’s GND Line or Body GND or any other similar device
since Lo(-) circuit is not GND.
*Equivalent
Circuit
1. At dispatch, it is set as 4㎃ with weight display “0” and 20㎃ with maximum load.
2.If you don’t get accurate output when you measure output current with DIGITAL MULTI-METER,
please do the detailed adjustment on VR₁(ZERO), VR₂(SPAN) on Analog Out PCB inside
the indicator.
※ Note: This Analogue out output is printed after converting displayed weight value
(Micro Process DATA) to Analogue value by D/A converter.
The accuracy of D/A converter is below 1/4000. Therefore, users should use the device
with accuracy below 1/3000
This is not suitable for the device that requires high accuracy over 1/3000.
