PD8-6210 ProtEX-MAX Explosion-Proof Analog Input Batch Controller

New product
 
More info

The ProtEX-MAX™ PD8-6210 offers all the functionality of the ProVu PD6210 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient SafeTouch® through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The PD8-6210 includes a 24 VDC power supply to drive the flowmeter and can be equipped with up to four internal relays and a 4-20 mA analog output.

Batch Controller

Rate Display Indication: 0 to 999999, lead zero blanking. "R" LED illuminates while displaying rate.
Total Displays & Grand Total Overflow: 0 to 999,999; automatic lead zero blanking. "T" LED is illuminated while displaying batch total and "GT" for grand total. Up to 999,999,999 with total-overflow feature. "" is displayed to the left of grand total overflow and LED is illuminated.
Batch Total Decimal Point: Up to five decimal places or none: d.ddddd, dd.dddd, ddd.ddd, dddd.dd, ddddd.d, or dddddd. Total decimal point is independent of rate decimal point.
Totalizer: Calculates total based on rate and field programmable multiplier to display total in engineering units. Time base must be selected according to the time units in which the rate is displayed.
Total Conversion Factor: 0.00001 to 999,999
Batch Preset: 0.00001 to 999,999 based on batch total decimal point.
Automatic Batch Restart Delay: 00000.1 to 999.9 seconds. The batch will automatically restart after completion of the last batch.
Grand Total Rollover: Totalizer rolls over when display exceeds 999,999,999. Relay status reflects the display value.
Grand Total Alarms: Up to seven, user selectable under Setup menu. Any set point can be assigned to grand total and may be programmed anywhere in the range of the controller for grand total alarm indication.
Note that Relay 1 should always be assigned to batch control (total).
Grand Total Reset: Via front panel button, external contact closure on digital inputs, automatically via user selectable preset value and time delay, or through serial communications.
Grand Total Reset Password: A grand total password may be entered to prevent resetting the grand total from the front panel.
Non-Resettable Grand Total: The grand total can be programmed as a non-resettable total by entering the password "050873".
Caution: Once the Grand Total has been programmed as "non-resettable" the feature cannot be disabled.

Relays

Rating: 2 or 4 SPDT (Form C) internal and/or 4 SPST (Form A) external; rated 3 A @ 30 VDC and 125/250 VAC resistive load; 1/14 HP (≈ 50 W) @ 125/250 VAC for inductive loads
Noise Suppression: Noise suppression is recommended for each relay contact switching inductive loads.
Relay Assignment: Relays may be assigned to batch control, sampling, rate, or grand total alarms.
Preclose: 0-100% of batch size, individually user programmable for each additional batch control relay beyond the first.
Alarm Deadband: 0-100% of span, user programmable
High or Low Alarm: User may program any alarm for high or low trip point. Unused alarm LEDs and relays may be disabled (turned off).
Batching Relay Operation: Single or (2 to 8) multi-relay batching with optional preclose for multi-stage operation. Each additional relay may be programmed with an individual preclose value.
Alarm Relay Operation: Automatic (non-latching), latching (requires manual acknowledge), sampling (based on rate or grand total), pump alternation control (2 to 8 relays), off (disable unused relays), and manual on/off control mode. Alarms are active only when the batch is running.
Alarm Relay Reset: User selectable via front buttons, digital inputs, or PC
   1. Automatic reset only (non-latching), when input passes the reset point or total is reset to zero.
   2. Manual reset only, when batch is stopped (latching).
   3. Manual reset only after alarm condition has cleared (latching)
Note: Front panel button or digital input may be assigned to acknowledge relays programmed for manual reset. This replaces one of the standard batch control function keys. Only the PAUSE/STOP key function is possible during a batch process, so manual reset may only be done when thecontroller is in STOP mode.
Deadband: 0-100% of span, user programmable
Time Delay: 0 to 999.9 seconds, on & off relay time delays. Programmable and independent for each relay.
Fail-Safe Operation: Programmable and independent for each relay.
Note: Relay coil is energized in non-alarm condition. In case of power failure, relay will go to alarm state.
Auto Initialization: When power is applied, relays will reflect the state of the input. Alarms are active only when the batch is running.
