DPharp EJA-E Series can perform remote settingand monitoring of measuring ranges, dampingtime constant, etc. through a HART protocolrevision5(HART 5) and revision7(HART 7) compliantconguration tool.

FEATURES Remote Ranging and Monitoring Functions

Ranges can be remotely set and monitored throughHART communication.

On-line Communication

Output signal and communication signal do notinterfere making on-line communication possible.

Enhanced Burst Mode and Event Notication(HART 7)

Advanced burst mode includes the variety oftransmission setting by specifying burst variables,update period, and message triger mode, and eventnotication function gives you alert signal basedon the status change in preset values and self-diagnosis.

Long Tag Supporting Up to 32 Characters(HART 7)

Long tag secures a better asset management withabundant digits in its software.

Self-DiagnosticPressure input outside of range limit, excessiveambient temperature, incorrect span setting etc. canbe diagnosed through HART communication.

HART protocol revision selectableSelectable from HART 5 and HART 7.

STANDARD SPECIFICATIONSFor items other than those described below, refer toeach General Specication sheet.

Specify the following when ordering.1. Model, sufx codes, and optional codes2. Calibration range and units: 1) Calibration range can be specied with range

value specication up to 5 digits (excluding anydecimal point) for low or high range limits within the

range of -32000 to 32000. 2) Specify only one unit from the above table, Unit ofCalibration Range.

3. Select linear or square root for output mode anddisplay mode.

Note: If not specied, the instrument is shipped set forlinear mode

4. Display scale and units (for transmitters equippedwith the integral indicator only)

Specify either 0 to 100 % or Range and Unit forengineering units scale:

Scale range can be specied with range limitspecications up to 5 digits (excluding any decimalpoint) for low or high range limits within the rangeof -32000 to 32000. Unit display consists of 6-digit,therefore, if the specied scaling unit excluding / islonger than 6-characters, the rst 6 characters will bedisplayed on the unit display.
