## **Inputs** ## U **Thermocouple** ## U **RTD** ## U **Process (DC Voltage and Current)** U **Strain Gage** ## **Options** ## U **Relay Output with Adjustable Deadband** U **Isolated or Non-Isolated Analog Output** U **Totally Programmable Color Display** U **Low-Voltage Power Options** ## **Panel Meters/Controllers** The OMEGA[®] DP25B Series meters have the biggest, brightest display of any[1] ⁄8 DIN panel meter. The user can select the display color: **ReD, AMBeR,** or **GReeN.** Along with the 4-digit, 9-segment display, these low-cost panel meters/controllers provide unparalleled accuracy in signal conditioning. Additional features include microprocessor-based operation; dual 5 A SPDT relays (optional); and isolated or non-isolated analog output in ranges of 0 to 10 Vdc, 0 to 20 mA, or 4 to 20 mA, which can be used for retransmission of the display value or as a proportional control output. The DP25 Series includes models with inputs for process (DC voltage and current), strain gages, thermocouples, and RTDs. ## **Thermocouple and RTD Models** These models combine versatility with ease of programming. The DP25B-TC is selectable for J, K, T, or J DIN thermocouples. The DP25B-RTD accepts Pt 100 Ω (0.00385 curve) RTDs. ## **SPeCIfICATIONS** **Display:** 4-digit, 9-segment, 21 mm (0.83") high red, amber or green LED (programmable) **Analog-to-Digital Technique:** Dual slope **Internal Resolution:** 15-bit **Polarity:** Automatic **Read Rate:** 3/s ## **Step Response:** 2 s **Relay Outputs (Optional):** 2 form “C” (SPDT) relays rated 5 A 250 Vac, programmable for active high/low alarms with latching/non-latching relays **DP25B, shown close to actual size.** ## _**Patented**_ _Covered by U.S. and International patents and pending applications_ ## **DP25B-TC (Thermocouple)** |**INPuT TyPe**

Features include easy front-panel scaling to virtually any engineering units, a remote tare function for weighing applications, and a hardware lockout to prevent unauthorized changes in setup. In addition, the DP25B-E meters feature built-in excitation in 4 user-selectable voltages, which makes them compatible with most transducers and transmitters. **DP25B-TC, programmed for optional green display, shown actual size.** ## **DP25B-RTD (RTD)** |**INPuT TyPe**|**RANGe**|**ACCuRACy**| |---|---|---| |RTD, 100ΩPt,
