aHR0cDovL2ZyZWVzaGlwLmNvLmtyThe mounting aperture of the potentiometer is 10mm
The length, width and height are 73*54*30MM and 61MM between the two holes. The two mounting holes are for M3 screws.
1. Features
1. Wide power supply voltage range: the input power supply is DC 15-30V DC.
2. The positive and negative polarities are connected to reduce the load resistance of the loop and avoid the situation that the current generator is out of control in some extreme cases.
3. Perfect protection function: with input voltage reverse connection protection, the instrument will not work if the power supply is reversed, and will not burn out due to 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 occasions where the current analog quantity 4-20MA output is required.
5. The current adjustment is very stable: the wire-wound potentiometer is used to adjust the current, and the adjustment is stable, which avoids the faults such as the sudden change of resistance often generated by the general carbon film potentiometer.
6. The potentiometer has a scale dial, which can quickly locate and identify the operating status 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 wiring methods.
9. The use of analog circuit design and precise reference voltage source fundamentally eliminates secondary pollution to the output current caused by AD conversion and DA conversion of single-chip or digital circuit design.
10. Wide range of application scenarios: The instrument has fixed ears, and the potentiometer can also be fixed somewhere in the customer's equipment as needed.
2. Technical indicators:
Supply voltage: 15V-30V
Output range: 3-22mA
Sampling resistance: less than 500 ohms
Output accuracy: +-0.5%
