I have a PLC capable of 0 - 10V output signal and a SSR (solid state relay) that is controlled via 4 - 32V is there some sort of chip that can be set to do this voltage translation or is there a circuit which could perform this task? Its 1 way communication, just on/off signal basically.

 

You don't need a circuit to translate the voltage. The output of the PLC will operate the relay as soon as it goes over 4V. I assume you mean that the output of the PLC switches from 0V to 10V. Or do you mean it gradually changes and can be any voltage between 0 and 10V.

 

It can change between 0 and 10 and based on this, the SSR will turn on and off in a different duty cycle, i.e. 0V should give minimum duty cylce at 4V and 10V should give max cycle at 32V.
