The Endevco 2792a 8-Channel Isotron Signal Conditioner is designed for use with Isotron accelerometers or any other integral electronics piezoelectric accelerometer which requires a constant current power supply with a compliance voltage. The signal Conditioner will accept a maximum input voltage range of +15V which is the sum or the quiescent accelerometer voltage and the accelerometer vibration output voltage.
