4-20mA Generator Adjustable Analog Quantity Current Signal Generator Module for Frequency Converter
Specifications:
Power supply voltage: 15V-30V
Output range: 3-22mA
Sampling resistance: less than 500 ohms
Output accuracy: ±0.5%
Features:
1. Power supply voltage range: the input power supply is DC 15-30V DC.
2. The use of positive and negative polarity access reduces the load resistance of the loop and avoids the situation where the current generator is out of control under certain extreme conditions.
3. Perfect protection function: with reverse connection protection of input voltage, the instrument will not work if the power supply is reversely connected, and will not be burned because of the reverse connection.
4. Standard current output range: 4-20MA current output can be generated by manually adjusting the potentiometer on the product, which is used for the occasion where the current analog 4-20MA output is required.
5. The current regulation is very stable: adopt wire-wound potentiometer to adjust the current, adjusting smoothly and avoiding the faults such as sudden resistance changes that are commonly produced by general carbon membrane potentiometers.
6. The potentiometer has a dial dial, which can quickly locate and identify the operating state of the equipment according to the scale.
7. The current output value can be fixed: the output current can be automatically constant at the set point according to the customer's adjustment, and can also be used as a constant current source. When used as a constant current source, the maximum current output does not exceed 22MA.
8. Compatible with 3 and 4 wire system wiring.
9. Adopt analog circuit design and precision reference voltage source to fundamentally prevent the secondary pollution of the output current caused by AD conversion and DA conversion of single-chip or digital circuit design.
10. A wide range of application: the instrument has fixed ears, and the potentiometer can also be fixed somewhere on the customer's equipment as needed.
Package List:
1 x Signal Generator
Note:
-The installation aperture of the potentiometer is 10mm.
-Length, width and height are separately 73*54*30mm, the two holes distance is 61mm. M3 screws are used for mounting two holes.
