LJTick-Divider

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, including adding offset to handle bipolar voltages.

The typical output range of the LJTD is 0-3.5 volts.  Here are the input ranges corresponding to 0-3.5 volts output, but keep in mind that some LabJack analog inputs are limited to 2.44 or 2.5 volts:

• LJTD-4: Vin 0 to 14.0 volts.
• LJTD-5: Vin 0 to 17.5 volts.
• LJTD-10: Vin 0 to 35.0 volts.
• LJTD-25: Vin 0 to 87.5 volts.
• LJTD-C: Custom slope and offset.

The LJTD can also be useful for digital signals by connecting to the DIO/DIO/GND/VS screw terminal block found on LabJacks such as the U3, U6, UE9, T8, T7, and T4.  The LJTD-4 works great for handling 12V or 24V logic signals.
