I would like to connect a sensor outputting 4-20mA PWM signal to an existing PLC that can only accept analogue 0-10V or 4-20mA signals as well as digital inputs.
The sensor (dissolved oxygen) outputs a PWM 4-20mA signal. Recommended settings for sensor connections a sampling rate below 3.5 kHz, an averaging over more than 1 s, and the use of galvanically separated inputs to avoid oscillations.
I believe I will need to convert the PWM signal to an analogue 0-10V or 4-20mA signal for the PLC. Can this be achieved simply or what converters can be recommended.
