Description:

Voltage to current module can 0-3.3V / 0-5V / 0-10V / 0-15V voltage signal into 4-20ma current signal;

In the process of circuit signal transmission voltage signal will increase with the transmission distance becomes weak, the use of current transmission can avoid the signal weakening.

Product Features:
1, power supply voltage: 7V ~ 30VDC (supply voltage must be greater than the need to convert the voltage).
2, need to convert the voltage signal: 0 ~ 2.5V, 3.3V, 5V, 10V, 15V, 24V.
3, output current: 4-20ma or 0-20mA.
4, zero and full scale can be adjusted (potentiometer adjustment).
5, with isolation, non-optocoupler isolation.
6, module size: 3.3 * 2.5cm

Input and output linear equations:
To convert the voltage and output current is a linear relationship, according to the zero point and adjust the range to determine the linear equation, two points to determine a straight line, two points are zero and adjust the range. Iout = K * V + b.
For example: 0-10V will be converted to 4-20mA, two points (0.4) and (10.20) which can determine the linear equation I = 1.6 * V +4.

Product manual:
1: get the baby power supply module connected to the right side of the three terminals.
2: zero: the conversion voltage signal is adjusted to 0V, adjust the zero reset device to make the output current 4ma. It is best to adjust the potentiometer knob with glue.
3: Tuning: adjust the conversion voltage to the required full-scale voltage (such as 3.3V, 5V, 10V, 15V), will adjust the full potentiometer so that the output current can be 20ma. The adjustment process will find the current output indicator from weak to strong. It is best to adjust the potentiometer knob with glue.
4: input voltage within the range, you can output the corresponding current, and the output current is negative for the power supply.

Example of adjustment:
For example: the supply voltage of 24V, need to 0-10V into 4-20mA
1: connected to the power supply voltage 24V, 24V positive connected to the right side of the three terminals, the negative side of the right end of the three terminals.
2: Zero: Two short terminals on the left side, adjust the zero knob to make the output (middle three terminals on the right) 4mA.
3: adjust the range: the need for conversion on the left side of the 10V, the left side of the need to convert the voltage of the negative pole. Adjust the span knob so that the output (middle three terminals on the right) is 20mA.
4: to change the voltage in the 0-10V change, the output current in the 4-20mA linear changes.
