All pulse or frequency inputs are easily displayed as rate. Easy setup with no programming or calculations required. Setup entries include time base, scale, offset. The D3870 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. Totalizer includes a selectable preset value and optional SSR 20 msec. output. The D3870 is packaged in an anodized aluminum case with a NEMA 4X front cover. One (1) Form A relay 240 VAC @ 1A that can be used as an alarm output is included.
