Description –

The Track and Hold accepts a 4/20 mADC signal and a Contact Closure. The output of the Track and Hold will Track the input as long as the Contact Closure is open. When the Contact is closed, the output of the Track and Hold will freeze and hold the output to the signal level when the Contact was closed. When the Contact is opened, the output of the Track and Hold will resume Tracking the input signal.
