The Series DPG-200 Digital Pressure Gage has a precise ±0.25% full scale
accuracy. The 4 digit digital display will reduce the potential for errors in readings by
eliminating parallax error commonly produced with analog gages. The DPG-200 is
packaged in a durable extruded aluminum case designed to meet NEMA 4X (IP66).
The unit is powered by 12 to 24 VDC/VAC and contains two alarm set points along
with a 4 to 20 mA process output. A four-button keypad allows easy access to features.
These features include backlight, peak and valley, auto zero and conversion of the
pressure units.
INSTALLATION
When installing gage always use 1˝ hex at the base of the housing to tighten the gage
to a mating fitting. Do not apply wrench to housing.

AL1S sets the relay on point, and AL1S - AL1D sets the relay off point. The relay’s output
functions in the direct acting mode, which means the relay activates with an increase
in pressure. In the above graph, an instrument with a 50 psi range has the AL1S set at
40. The relay will turn on at 40 psi increase. The AL1D is set at 30. The relay will turn off
at 10 psi decrease (40 - 30 = 10).

TIME
AL2S sets the relay on point, and AL2S + AL2D sets the relay off point. The relay’s output
functions in the reverse acting mode, which means the relay activates with a decrease
in pressure. In the above graph, an instrument with a 50 psi range has the AL2S
relay turn on at 10 psi decrease. The AL2D is set at 30. The relay will turn off at 40 psi
increase (10 + 30 = 40).
