MODEL KBSI-240D Signal Isolator KB Part No. 9431

2021-04-07
The KBSI-240D Signal Isolator is used to isolate, amplify and condition DC voltage and currentsignals from any source (motors, tachs and transducers) which will drive most variable speedmotor controls with a voltage following input. The maximum output voltage of the isolator is 10volts, which is a linear function of the input signal.
The KBSI-240D is versatile since it can accommodate a wide range of input voltages (0 - 25*,0 - 120 and 0 - 550V DC) and, in addition, a wide range of input current signals (4 - 20 mA,10 - 50 mA and 1 - 5 mA). The Voltage/Current (“VLT/CUR”) jumper is used to change the KBSI-240D from a voltage to current input.
A built-in power supply enables the KBSI-240D to be controlled with a 5KΩ remote poten-tiometer (connect potentiometer to terminals “P1,” “5” and “6” – see page 9). The potentiome-ter can also be wired for Auto/Manual Operation.
*The input range of 0 - 25V is the maximum voltage that can be applied to terminals “5” and“6”. The minimum input voltage is 0 - 5 volts, which can achieve an output voltage of 0 - 10volts. The unit is factory calibrated so that a 0 - 10V DC input yields a 0 - 10V DC output.
