Series-DPMA-500

Supported Applications

The Dwyer Series DPMA-5 LCD Digital Panel Meter is designed to display process values from transmitters measuring pressure, humidity, temperature, voltage, current, wattage, or power factor. The series accepts standard industrial signal inputs including 0 to 10 VDC, 0 to 5 VDC, and 0 to 200 mVDC.

Operating Conditions & Performance

The Series DPMA-5 operates within an ambient temperature range of 32 to 122°F (0 to 50°C) with a storage temperature capability from -4 to 158°F (-20 to 70°C). Accuracy is specified as ±0.05% FS + 1 count for the DPMA series, with an input impedance of 390kΩ nominal. The meter features a conversion rate of 3 per second and requires approximately 10 minutes typical warm-up time.

Power requirements are met by a separate external supply of 12 VDC or 24 VDC connected to the screw terminals marked "+pwr-". If backlighting is utilized, it requires a dedicated 24 VDC power supply at 35 mA typical, connected to terminals identified with "+B/L-".

Configuration Options

The Series DPMA-5 provides configurable options for display visibility and engineering units within its standard 1/8 DIN package. Key capabilities include:

• Display Resolution: 3-1/2 digits, 7 segments with a 1" (25.4 mm) H height.
• Segment Colors: Available in red, amber, or green for easy viewing at a distance; black and blue are available on other series models within the family manual context but not explicitly listed as stocked variants here.
• Engineering Units: Field selectable units include °F, °C, %, PSI (DPMA-XXX) or V, A, KW, PF (DPMA-XXXXP).
• Polarity & Decimal Points: Automatic polarity with a "-" displayed for negative values; 3-position user-selectable decimal points.
• Mounting: Snap-in panel mount or clamp installation with gasket included.

The model number structure follows the format: DPMA-XXX - <Engineering Units> - <Decimal Point Position> - <Polarity> - <Display Color> - <Backlight> - <Power Supply> - <Signal Input> - <Mounting> - <Connection> - <Agency Approvals>.

Key Product Differences

The Series DPMA-5 is distinguished from other models in the broader Dwyer digital panel meter family (DPMW, DPM, DPML) by its specific housing and display characteristics. While the data sheet covers a wider range of inputs including 4-20 mA for current measurement across all series families, the Series-DPMA-500 variants listed are configured specifically for voltage inputs.

Within the broader family documentation:

• DPMW models utilize a window mount design that sits flush within the panel cutout using two screws and feature 3-1/2 digit displays with 0.45" (11.4 mm) H segments.
• DPML models offer snap-in bezel mounting with a higher resolution 4-1/2 digit display, also with 0.45" (11.4 mm) H segments and 4-position decimal points.
• DPMX-4XX(P) variants are powered by the control loop for current inputs, whereas DPMX-5XX(P) require an external 12 VDC or 24 VDC supply for voltage inputs.

The Series DPMA-5 is not field serviceable; units requiring repair must be returned to the manufacturer. Agency approvals include RoHS compliance.
