Universal Flow Totalizer & Tachometer/Rate Meters
Precision Digital's new Universal Rate/Totalizer Batch Controller 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.

Specifications

Model PD692 specifications | Model PD693 specifications

ISOLATION: AC power 1500 VAC; DC power: 500 VDC.

TOTALIZER: Calculates total based on rate and field programmable multiplier to display total in any engineering unit.

TOTAL RESET: Via front panel ENTER button, external contact closure at terminals RST and COM, or automatically via user selectable preset value #2.

PEAK HOLD: Captures the peak rate and displays it via the front panel ENTER button.

PEAK HOLD INDICATION: Front panel flashing "R" LED.

LOW FLOW CUTOFF: 1 count to 100% F.S., user selectable. To
disable low flow cutoff, program cutoff value to zero.

ROLL OVER: Totalizer "rolls over" when display exceeds 999,999. Relay status reflects display.

NON-VOLATILE MEMORY: All programming values are stored in non-volatile memory for ten years if power is lost.

LOCKOUT: Jumper at rear of instrument restricts modification of calibration values.
ENVIRONMENTAL: Operating temperature range: 0 to +65^oC
Storage temperature range: -40 to +85^oC
Relative humidity: 0 to 90% non-condensing

FRONT PANEL: NEMA 4X, panel gasket provided.

UL FILE NUMBER: E160849; 508 Industrial Control Equipment.

PD692

ANALOG INPUTS: Field selectable: 4-20 mA, 0-20 mA, 0-5 V, 1-5 V, 0-10 V.

CALIBRATION: May be calibrated using internal calibration or by applying an external calibration signal.

CALIBRATION RANGE: 4 mA (1 V) input may be set anywhere in range of the meter. 20 mA (5 V) may be set anywhere above or below 4 mA (1 V) input.

LOOP POWER: (AC powered units only) Isolated, up to 20 mA at 24 VDC regulated +/-5%, noise less than 10 mVpp. Max. loop resistance of 1200 ohm. Use to power either external transmitter or 4-20 mA output signal.

LINEAR INPUT ACCURACY: 0.05% of calibrated span, +/-1 count.

SQUARE ROOT EXTRACTION ACCURACY: +/-0.1% F.S. +/-1 count from 10-100% of flow, +/-1% F.S. (0-10% flow).

MINIMUM INPUT SPAN: 1.6 mA between points.

INPUT IMPEDANCE: Voltage ranges, greater than 300 Kohm; current ranges, 100 ohm.

PD693

FREQUENCY INPUTS: Field selectable: Pulse or Square Wave 0-5 V or 0-12 V @ 30 kHz; TTL; Open Collector 4.7 Kohm pullup to 12 V @ 30 kHz; Switch Contact 4.7 Kohm pullup to 12 V @ 40 Hz.

LOW VOLTAGE/MAG PICKUP (isolated): Sensitivity: 125 mV p-p; Hysteresis: 30 mV.

CALIBRATION: May be calibrated using K-factor scaling, internal calibration or by applying an external calibration signal.

OUTPUT POWER: (AC powered units only) Field selectable, isolated, 12 VDC @ 50 mA for sensor supply, or 24 VDC @ 20 mA regulated �5%, noise less than 10 mVpp. Max. loop resistance of 1200 ohm.

ACCURACY: +/-0.1% of full scale.

MINIMUM INPUT SPAN: 2.0 Hz between points.

INPUT IMPEDANCE: Pulse Input: Greater than 300 Kohm @ 1kHz Open Collector/Switch Input: 4.7 Kohm pull-up resistor to 12 V.

Relays

RATING: 2 or 4 SPDT (form C); rated 2 Amp @ 30 VDC or 2 Amp @ 250 VAC resistive load; 1/14 HP @ 125 / 250 VAC for inductive loads.

TOTALIZER PRESETS: 2,
Relays #1 and #2 are assigned to total and may be programmed anywhere in the range of the meter; relays trip when total exceeds preset value and reset when total is reset to zero. #2 preset is user programmable to reset total to zero when preset value is reached. A delay of between 1 and 999 seconds can be programmed on the PD693 while the PD692 has a fixed value of 10 seconds before relay #1 and #2 reset.

PRESET VALUE TRACKING: Relay #1 can be programmed to trip at any point below relay #2 preset value. If relay offset mode is selected relay #1 will always trip at a programmed offset value before relay #2 trips. ex. if the relay offset is set at 10 then relay #1 will trip at 10 counts before relay #2.

RATE RELAYS: 2,
#3 & #4 assigned to rate, any combination of high or low alarms.

RATE ALARM DEADBAND: 0-100% of full scale, user selectable.

RATE RELAY RESET: User selectable, relay #3 and #4

a. Automatically when the input passes the reset point.

b. Automatically + manually (via user supplied external contact closure at terminals ACK and COM, or front panel ACK button). Manual reset resets all manually resetable relays.

FAILSAFE OPERATION: The relay coils are energized in the non-alarm condition. In the case of a power failure, the relays will go to the alarm state.

AUTO INITIALIZATION: When power is applied to the meter, relays #1 and #2 will reflect the state of the accumulated Total value in memory, relays #3 and #4 will reflect the state of the input to the meter.

Isolated 4-20 mA Transmitter

CALIBRATION RANGE: Anywhere in range of meter, 501 count minimum span.

OUTPUT LOOP RESISTANCE:
