9-5 OP-07 ANALOG OUTPUT

The OP-07 analog output option is for sending the weight data to an analog input unit. The output is a 4 to 20 mA

current output proportional to the display reading.

The output data is updated in synchronization with the display update.

Interface Specification

Current output 4 to 20 mA

Applicable load resistance

0 to 520 Ω

Resolution Approximately 1 / 3000

Non-linearity +/- 0.1% F.S or less

Zero point: +/- 0.02 %FS/ °C or less

Temperature coefficient

Sensitivity: +/- 0.02 %FS/ °C or less

SETTING METHOD

Set the weight value at a 4 mA output point in ANF-02 and that at a 20 mA output

point in ANF-03, ignoring the unit of weight.

Outputting 4 mA at 0.0 kg and 20

mA at 1,000.0 kg. (Full line in the

figure at the left )

ANF-02 = 0.0 kg

ANF-03 = 1000.0 kg

Outputting 20 mA at 0.0 kg and 4 mA at 1,000.0 kg. (Dotted line in the

figure at the left)

ANF-02 = 1000.0 kg

ANF-03 = 0.0 kg
