Display
|
Pressure reading: 5 digits with 0.5 in (12.7 mm) character height
Full scale indicator: 2.5 digits with 0.25 in (6.35 mm) character height

|
Pressure Bar Graph
|
In addition to the numeric pressure indication, the DPI 104 LCD display contains a circular twenty segment bar graph to provide the user with a quick visual estimation of pressure from 0 to 100% full scale output. The bar graph increments represent 5% of the user-selectable range.

|
Minimum/Maximum Values
|
The minimum and maximum pressure values can be displayed on the DPI 104. This function can be enabled/disabled, and reset by the user.
|
|
Switch Test
|
The DPI 104 features a switch test function that will capture and display the open and closed values from an external pressure switch. Maximum switch impedance 200 O.
|
|
Voltage Output
|
The DPI 104 can be programmed to provide a 0 to 5 V output signal that can be configured as directly proportional to the pressure shown in the display or set to a fixed value. The voltage output mode provides 0.1% FS accuracy from 50 mV to 5 V.
|
|
Alarm Output
|
The alarm output consists of an open drain field effect transistor (maximum current 250 mA, maximum voltage 24 VDC)
|
|
Adjustable Mounting Positions
|
For added convenience, the DPI 104 housing will rotate 320° around the pressure fitting and the faceplate can be rotated in any orientation for optimum visibility.
|
|
Menu Lock
|
To guard against unauthorized menu access, the DPI 104 features a menu and tare lock function
|
|
RS232 Interface
|
Serial communications are provided to allow transfer of data to a PC with the optional serial lead (IA4090-2- V0). Using this link all menu commands and display data are available via an ASCII command set or the optional SiCal Pro Software.
