Description –

 

The Rate Limiter accepts a 4/20 MADC signal and provides a 4/20 mADC output signal that is limited to that rate at which it can change. The Rate of Change is adjustable from 0/60 seconds. For example, if the Rate of Change is set to 30 seconds, it will take 30 seconds for the output to go from 4 to 20 mADC based on an input signal step change of 4 to 20 mADC.
