Digital Panelmeter PM2

Product catalog summary
Product Description: The Digital Panelmeter PM2 is designed for displaying signal voltages and is suitable for force measurement values when used with load cells and amplifiers. It features a 3½-digit LCD display, automatic zeroing, built-in scaling, and a DIP switch selectable decimal point. The front panel bezel meets IP 65 standards, making it suitable for front panel mounting or switch cabinets.
Special Features: The panelmeter includes a 3½-digit LCD display, automatic zeroing circuit, built-in scaling, and a DIP switch for decimal point selection. It is designed to meet IP 65 standards for the front panel bezel.
Technical Data: The panelmeter supports a nominal input voltage of ±10 V DC, with a maximum input voltage of 75 V DC for the 199.9 mV range and 300 V DC for other ranges. It has an input resistance of 1 MΩ, a resolution of 3½ digits, and a measuring error of ±0.1% ±1 digit. The reading rate is 2.5 readings per second with a response time of 1.5 seconds. The power supply ranges from 9 to 28 V DC, with a maximum current of 4 mA. Operating temperatures vary based on the power supply voltage.
Protection and Certifications: The front panel bezel meets IP 65 standards. The device complies with EMC emissions (EN 500081-2) and immunity (EN 500082-2) standards and is UL certified for the USA and Canada.
Adjustment and Calibration: The panelmeter allows for real-time display adjustments using DIP switches. The division factor is determined by the nominal input voltage, display value, and decimal point position. Factory adjustment is set to display 10.00 at 10 V input voltage. An example adjustment is provided for setting the display to 1800 with a 10 V DC input.
Scope of Supply: The package includes the electronic unit, fastening material, and gasket. An optional version with red backlighting is available (Ordering Data: PM2-D).

Digital Panelmeter PM2-1

Product Description Electronic unit - Fastening material - Gasket Special Features - Option D: with red backlightning  Automatic zeroing circuit  Built-in scaling provided  DIP switch selectable decimal point  Front panel bezel meets - IP 65 Ordering Data: PM2-D Typ Option Panelmeter cut-out: DIN 68 mm x 33 mm. Fastening with mounting brackets. This panelmeter is primarily used for displaying signal voltages. In conjunction with load cells and amplifiers this unit is equally well suited for the display of force measurement values. The unrestricted selection of the decimal point and the scaling of the signal allow the real-time display of other values for instance web tension forces. The enclosure is suitable for the front panel mounting or for switch cabinets.
