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, RTD, Dual/Differential Thermocouple, Dual/Differential RTD, Process (DC voltage and current) Strain Gage, pH, ORP.
The DP25-RTD accepts 3-wire 100 ohm platinum RTD inputs (alpha = 0.00385) and has an accuracy of ±0.5°C. Standard features include resolution of 0.1° or 1.0°, °F or °C indication.
