Universal Rate/Totalizer Batch Controllers

Precision Digital's new Universal Rate/Totalizer Batch Controllers may be used to display rate and total as well as provide simple automatic or manual batch control. Models are available for analog inputs such as 4-20 mA or frequency/pulse inputs such as pulse, open collector or switch closures. These meters feature a full six digit display, programmable time base of second, minute and hour, as well as a user programmable multiplier out to five decimal points. They also provide 24 VDC excitation for analog inputs and up to 50 mA for frequency/pulse inputs.
