Displays //D3820/30 299 P r o c e s s Me t e r w i t h T o t a l i z er The Digitec Series D3800 Panel Meters offer many features and performance capabilities to suit a wide range of industrial applications. The D3820 and D3830 are available in the ranges of 4-20mA, 0-10 VDC, or 0-5VDC. 10 VDC and 24 VDC excitation is available as an option. These controllers include a 30 point linearization capability for compensation of non-linear processes. The D3820 and D3830 provide two programmable, (PEAK, VAL), reading memory. The D3830 Totalizer can be used to compute a time-input product. This can be used to provide readout in totalized flow, batch or weighing operations. The units can have up to 4 setpoint alarms assignable to Rate, Totalizer (3830), or both Rate and Totalizer. Four front keys are easily programmed for special functions allowing quick access to alarms, view Peaks, reset totals or switch scaling from gallons to barrels. The 3820/30 comes standard with (1) Form A relay 240 VAC @ 1A that can be used as an alarm output. PRODUCTION RATE: Units per second/minute/hour computed and displayed in the time of one input period. Also computed in dozens, gross, or other packaging units. ROTATION: Speed indicated as RPS, RPH, RPM, or as linear motion (feet/second, meters/hours, etc). PUMP UP/DOWN: The alternating relay option allows the 3820 to control a Duplex pumping application. The unit has a user programmable time delay to allow a delay of both pumps coming on after a power outage, The 3820 also can provide additional low and High Alarms. TOTALIZER: Totalizer mode displays accumulated total of units or events (ie,-gallons, pounds. etc.) since power-up or last reset a low flow cutoff setting is available. Exponent mode is available to totalize up to 999E99. An optional Totalizer SSR 20 msec. pulse output with selectable automatic reset of total value allows batching operations. FLOW: Sensor input scaled to gallons/ minute, liters/hour, pounds/ minute, ACFM. etc. D3820/D3830 \\\DIMENSIONS (INCHES/MILLIMETERS) • 6-Digit Red LED Display • 1/8 DIN extruded aluminum case • D3830 Totalizer Optional with a Exponent Mode • NEMA 4X (IP65) Front Panel • Four programmable alarm setpoints, up to 4 relay outputs • Selectable update rate of .1, 2, 10, 20/SEC • Four programmable function keys • Alternating Relay Function (Alarm 1 and Alarm 2) • Square Root, Flume, Weir readings • 30 point linearization
