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 12-24 VDC/VAC and contains two alarm set points along with a 4-20 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.

Alarm 1
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).

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).
