The OMEGA DP25B series Digital Panel Meters feature the biggest brightest display of any 1/8 DIN panel meter. The user can select the display color: RED ,AMBER, or GREEN. PANEL METERS with Relays and Analog Output The popular DP25B series are accurate, economical, and easy to program. The DP25B series feature a big bright four digit display plus optional dual 5 amp Form C (SPDT) relays and a choice of isolated or non-isolated analog output. The scalable 0-10 Vdc, 0-20mA, or 4-20 mA analog output can be used as a retransmission of the display value or as a proportional control output as required. The microprocessor based DP25B series includes instruments for Thermocouple, Process (DC voltage and current), and Strain Gage.
The DP25B process meter accepts a wide variety of DC voltage and current inputs to cover any typical process application. Standard features include easy front panel scaling to virtually any engineering units, selectable excitation of four voltages to work with most transducers and transmitters, front panel and remote tare function for weighing applications, and a hardware lockout to prevent unauthorized changes in setup. Four full digits and simplified scaling via the front-panel pushbuttons make it easy to set the display to read in any engineering units.
