DIS475B-R process indicator monitors frequencies in the range 12 to 50 kHr and provides a 3.5 digit display that can be calibrated to allow display of the process in engineering units. Manufactured by Wilkerson Instrument Co. Inc., the indicator accepts input levels from 150 mV to 160 V p-p and also provides a pull-up resistor for open collector transistor inputs. DIS475B-R mounts through the front panel in a 1/8 DIN cutout.
