Bulletin A-34A Series DPG-200 Digital Pressure Gage ® Specifications - Installation and Operating Instructions 2-3/8 [60.45] 1-5/8 [40.39] 3 [76.20] 3-5/8 [91.39] 1/4 NPT 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.

BUTTON OPERATION See menu page. Zeros display if within ±4% F.S. of zero. See units chart below. See peak/valley. PEAK VALLEY PEAK • Highest pressure since peak and valley was reset. • Zero button resets both peak and valley to the current pressure. VALLEY • Lowest pressure since peak and valley was reset. • Zero button resets both peak and valley to the current pressure.

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). ©Copyright 2019 Dwyer Instruments, Inc. DWYER INSTRUMENTS, INC. P.O. BOX 373 • MICHIGAN CITY, INDIANA 46360, U.S.A. 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).
