DPI 104Specifications

Pressure Bar Graph
In addition to the numeric pressure indication, the
DPI 104 LCD display contains a round 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 userselectable
Display Update
Two times per second
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 .
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 (IA090-1-VO).
Using this link all menu commands and display data are
available via an ASCII command set or the optional SiCal
Pro Software.
Network Capability
Up to 99 DPI 104 instruments can be connected together
in a daisy chain-configured network.
DPI 104
Universal Pressure Module (UPM) Capability
UPM modules can be connected to the DPI 104 to
enhance the accuracy and extend the pressure range.
The DPI 104 is supplied with a 9V alkaline battery, type
MN1604. For increased performance a 9V lithium battery
(not supplied by GE) is suggested.

CE marked
SiCal Pro Software
This software package allows the user to control the
DPI 104 remotely through a virtual instrument panel on
the computer screen. The calibration data can be logged,
viewed and printed in graphical format or as a
calibration certificate.
System Requirements
Minimum Intel Pentium with Windows® 95 or higher.
