Original Press Release:

3870 Smart Frequency Input Rate / Totalizer Digital Panel Meter Series

Lancaster, PA. . . . .ATC's Instrumentation Division announces their new 3870 SMART Frequency Input Rate/Totalizer digital panel meter series, ideal for the Process Control Industry.

The 3870, 6-digit frequency input rate/totalizer with its rich option set of up to four relay outputs, (one Form-A 5 amp standard and three Form-C 5 amp optional), four analog outputs or RS 232 serial communications is a high performance and easy to use microprocesser based process controller that provides fast, accurate rate measurements even with very low pulse rate inputs (as low as one pulse per 100 seconds). All pulse or frequency inputs are easily displayed as rate with simple setup that requires little programming and no calculations. Setup entries include time base scale, offset and K factor.

The 3870 features a 6-digit totalizer mode that can be independently scaled and displayed. The totalizer mode can accumulate totals for units or events (i.e.: gallons, revolutions, pounds, etc.) since power-up or last reset.

The totalizer includes a selectable preset value and optional open collector output that can deliver a scaled pulsed output to other equipment such as PLCs or other controllers. 16-point linearization is a standard feature as is the NEMA 4 front bezel and rugged aluminum case.
