## **Panel Meters** 

The OMEGA[®] DP25B Series features the biggest, brightest display of any[1] ⁄8 DIN panel meter. The user can select the display color: **RED** , **AMBER** , or **GREEN** . 

Unparalleled accuracy in signal conditioning is available in this economical series of panel meters/ controllers. The series has a 4-digit, 9-segment display plus optional dual 5 A, SPDT relays (Form “C”) and a choice of isolated or non-isolated analog output. The scalable 0 to 10 Vdc, 0 to 20 mA, or 4 to 20 mA analog output can be used for retransmission of the display value or as a proportional control output, as required. The microprocessor-based DP25B series includes instruments for process (DC voltage and current) strain gage, thermocouple, and RTD. 

## **Specifications**
