Description:
The DP-650 Series is an ultra-compact, low-power LCD meter requiring only 15mW of power. This meter is ideal for applications requiring a highly reliable LCD display in a small package. The snap-in bezel packaging enables easy and rapid installation of the meter. The simplicity of design, overvoltage protection, and low power consumption all contribute to the high reliability of this device.
Three input voltage ranges are available: ±200mV, ±2VDC, and ±20VDC. A 4 to 20mA current input adapter (DP-670) is also offered. Automatic polarity, overrange indication, adjustable decimal point, and display HOLD are standard features. The DP-650 Series employs a dual slope integrating A/D converter, and operates from an internal 100mV reference via a precision DC-to-DC converter. Typical accuracy is ±0.1%.
Note: The DP-650 is also available with a process board, as the DP-670.
Features:
- Convenient snap-in bezel package
- Very low power consumption (5VDC @ 3mA)
- Differential input, 3 voltage ranges
- 0.1% typical accuracy
- User-selectable decimal point
- Hold-display function
- Overvoltage protection
- Quantity discounts
Technical Notes:
- The connection shown utilizes differential inputs. For single-ended operation, INPUT(-) is strapped to GND. If the signal is isolated from the power source, connect INPUT(-) to GND either directly or through a 10K resistor network as shown to reduce common mode errors.
- Display holds reading when HOLD is high (+5V). Readings are updated when HOLD is low or floating.
- The decimal point is user selectable by connecting the decimal point pins (4, 5, or 6) to DP COM (pin 3).
- Full-scale input span is adjusted prior to shipment. Further calibration is possible by adjusting the trimpot mounted on the back of the DPM.
- Unused pins should be left open.
Application:
- Portable/mobile equipment
- Medical instruments
- Avionics/aerospace systems
- Office equipment
