신호변환기(신호감쇄기) The LJTick-Divider (LJTD) is a signal conditioning module designed to take two single-ended higher voltage analog signals, and divide them by a specified value. These devices come in divide by 4, 5, 10, 25, and "C" or Custom. The 4-pin design plugs into the standard AIN/AIN/GND/VS screw terminal block found on LabJacks such as the U3, U6, UE9, T7, and T4. The use of large resistors and a precision op-amp buffer provides an input impedance of 1 megaohm. The resistors can be customized to allow for a wide range of configurations. The LJTD can also be used with higher voltage digital signals. The LJTD-4 works for 12V or 24V logic. A 12V signal will divide down to about 3.0V which is a logic high for any LabJack. A 24V signal (or even much higher voltages) will result in about 3.5V, as that is the max output of the LJTD, and that also is a good logic high for any LabJack.
