Description: As depicted in the image, when the output current surpasses 40mA, the internal resistance of 50Ω in the XTR110 (R9) must be substituted with an external resistance, REXT. This external resistance is connected between pins 13 and 16. The value of REXT can be calculated using the formula REXT = R9 × (original span / required span). For instance, if the original span of the XTR110 is 20mA and the desired span is 10A, and R9 is 50Ω, then...
The XTR110 is a precision current transmitter designed for industrial applications, capable of converting a low-level input signal into a proportional current output. In scenarios where the output current exceeds 40mA, it becomes necessary to modify the internal resistance to accommodate higher current levels. The internal resistance, R9, which is fixed at 50Ω, limits the maximum output current. By replacing R9 with an external resistor, REXT, the circuit can be adjusted to handle higher currents without compromising the performance of the XTR110.
To determine the appropriate value for REXT, the ratio of the original span to the required span must be calculated. The original span is defined as the maximum output current the device is designed to produce under normal conditions, while the required span is the new maximum output current desired for the application. For example, if the original span is 20mA and the required span is 10A, the calculation would be as follows:
REXT = 50Ω × (20mA / 10A)
This calculation effectively scales the internal resistance to match the new output requirements. It is critical to ensure that REXT is connected properly between pins 13 and 16 to maintain the integrity of the circuit. Additionally, care should be taken to select a resistor that can handle the power dissipation associated with the higher output current.
In summary, by replacing the internal resistance R9 with an appropriate external resistor REXT, the XTR110 can be effectively configured to output higher currents, thus enhancing its versatility for various industrial applications. Proper calculation and implementation of this modification are essential for achieving the desired performance without damaging the device.As shown in the picture, when the output current exceeds 40mA the internal resistance 50? in the XTR110 (R9) should be replaced by external resistance REXT. REXT is connected between the 13 foot and 16 foot. REXY=R9(original span/required span). For example, the XTR110 in the picture`s original span is 20mA and now the required span is 10A. If R9=50?, then..
