The DPI series electronic pressure measuring devices are engineered for building automation in HVAC/R industry. The most technologically advanced and versatile electronic differential pressure switches on the market, combining up to two relay outputs and 0–10 V output options.
The DPI includes the following field selectable features:
• Configurable Switching Point: Open on rise or fall in pressure
• Hysteresis of setpoint
• Measurement units (Pa, kPa, mmWC, inWC, mbar)
• Measurement range (4 ranges per model)
• Output signal (0−10 V, NO/NC)
• Span and zero point calibration
Applications
DPI series devices are commonly used in HVAC/R systems for:
• fan, blower and filter monitoring
• staircase pressure monitoring and alarm
• pressure monitoring in cleanrooms
• boiler pressure monitoring and alarm
Electrical interface:
• Supply voltage: 21–35 VDC / 24 VAC ± 10 %,
with AZ option: 24 VDC / VAC ± 10 %
• Current consumption:
35 mA + relays (7 mA each) + AZ (20 mA) +
0…10 V output (10 mA)
• Output signals, basic version:
