| DP-650 Series Miniature LCD Display Digital Panel Meters 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 4-20mA 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%. 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 1. 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. 2. Display holds reading when HOLD is high (+5V). Readings are updated when HOLD is low or floating. 3. The decimal point is user selectable by connecting the decimal point pins (4, 5, or 6) to DP COM (pin 3). 4. Full-scale input span is adjusted prior to shipment. Further calibration is possible by adjusting the trimpot mounted on the back of the DPM. 5. Unused pins should be left open. Applications * Portable/mobile equipment * Medical instruments * Avionics/aerospace systems * Office equipment Model DP-650 DP-652 DP-654 APS-5 C-10 Ordering Description Information Miniature DPM LCD 200mV Miniature DPM LCD 2V Miniature DPM LCD 20V 120V AC to 5V DC Power Supply Connector - 10 pin 6 ACCULEX * 1-888-472-6676 * Fax 1-888-210-0119 * acculex.com DP-650 Series Dimensions Pin No. 1 2 3 4 5 6 7 8 9 10 Connections Pin Name V+ GND DP COM DP1 DP2 DP3 INPUT(+) INPUT(-) NC HOLD Description +5V power supply Power supply ground Decimal point return 1XX.X (connect to DP COM to turn on) 1X.XX (connect to DP COM to turn on) 1.XXX (connect to DP COM to turn on) Positive input signal Negative input signal (see Technical Note 1) No connection required Hold last display (see Technical Note 2) Specifications Display Digits 31/2 (1999 count) Type 7-segment LCD Digit Height .39in (10mm) Polarity Indication Automatic - for neg input Decimal Point 3 position selectable Overrange Indication 1--- for positive, -1--- for negative Other Features/Options Display hold function Signal Inputs Configuration Bipolar, differential Full-Scale Input 200mV, 2V, 20V Input Offset Adjustment Auto zero Input Impedance 10M (200mV), 1M (other ranges) Common Mode Range 1VDC Common Mode Rejection >86dB Overrange Protection 350VDC (100 VDC for 200mV range) Input Bias Current 1pA typical, 100pA max Control Inputs Decimal point select, hold function Performance Sampling Rate 3.3 readings/s Accuracy (0.1% + 2 counts) typ, (0.2% + 2 counts) max Warmup, typical 10 min Temperature Drift, typical 100 ppm/C Power Supply Requirements Supply Voltage +5VDC 5% Supply Current, typical 3mA Physical Package Style Snap-in bezel mount Dimensions 2.30 x 1.10 x .71 Panel Cutout 2.22 x 1.04 Weight 0.7oz (20g) Connector C-10 (10-pin) optional Bezel Snap-in bezel included Environmental Requirements Operating Temperature 0 to 50C Storage Temperature -10 to 60C Relative Humidity 0 to 95% non-condensing inches (mm) ACCULEX * 1-888-472-6676 * Fax 1-888-210-0119 * acculex.com 7 |
