مبدل ولتاژ به جریان 4 تا 20 میلی آمپر

Features:

1.1  Size of PCB: 5cm*3cm, Diameter of fixing hole: 3mm, Mounting dimension of fixing  hole: 4.4cm*2.5cm

1.2  Product model: BSC_VTOC_V1.3

1.3  Consumption and maximum load

Without load: consumption<10mA (testing condition: supply voltage=12V, control voltage angling input)

With load: output maximum load <=0.3W (testing condition: supply voltage=24V, current output=20mA)

1.4  Power Voltage Specification: DC 0-10V (control voltage) convert to 4-20mA, scope of supply voltage: 12V-30V

1.5 Precision: Output 4-20mA, Current precision≤0.01mA

Calibration:

(1)    Zero Calibration: adjust control voltage to 0V and adjust zero calibration potentiometer to get 4mA output current. You can fix the potentiometer knob by adhesive.

(2)    Full Scale calibration: adjust control voltage to required full scale voltage (for example 2.5V, 3.3V, 5V, 10V) and adjust full scale calibration potentiometer to get 20mA output current. The current output indicator lamp gets brighter during the adjustment.You can fix the potentiometer knob by adhesive.

(3)    After calibration, if you find control voltage is 0V but current output is not 4mA, you need to repeat calibration process.
