I have few DC voltages to be measured which are less than 10V.
For measuring I'm using the data acquisition module which has the range of 0 to 10 V.
In case at any situation if the DC voltages goes more than 10 V they damage the DAQ device.
so I want voltage clipper circuit that passes as it is ..only less than 10V.
at any moment if the signal is more than 10V the voltage must be clipped for safeguarding my DAQ device.

Any circuit/ advise .. please share !!

A diode to a 10 volt reference ( the supply voltage perhaps ) is a standard approach. The diode is usually biased off. You will need an input resistor ( or input impedance ) prior to the diode. Voltage will go to 10 v + 1 diode drop. This is usually Ok, but check the data sheet.
