Product details
1、 Product Overview
The SNDEB-AI/AU series AC current transmitter converts AC signals from AC transformers into standard process signals for central monitoring of motors, pumps, or heating networks in DCS, monitoring power lines and their currents.
High reliability isolation of input, output, and power ports.
2、 Signal adjustment and explanation
When the product is working normally, the ON indicator light on the panel should be on.
There are two potentiometers on the product panel for signal adjustment
When conducting the following debugging, please power on and preheat the product for 30 minutes to achieve optimal stability.
1. Zero signal adjustment: When the input signal is zero, the output signal of the transmitter can be adjusted to the desired minimum value by adjusting the zero potentiometer.
2. Full scale signal adjustment: Input the signal to full scale (maximum value), and adjust the transmission signal to the required maximum range value through the range potentiometer.
3. Repeat operations 1 and 2 until they reach the desired value.
