產品描述
OMEGA’s new universal panel meter delivers high performance in a 1/8 DIN size for panel mount, and integration in a wide range of applications. The DP20 accepts universal inputs, including thermocouple, RTD, process (mA & Vdc), resistance, and true RMS voltage and current. By configuration, it will work as an AC and DC voltmeter (up to 400 V) and AC and DC ammeter (up to 5 A) offering application flexibility for process control and industrial requirements. A single universal power supply allows this unit to be suited for global use.
The optional relays, analog output, and Modbus? RTU serial communications provide customization, control and communication capability. Additional features of the economical DP20 panel meter include scaling, NEMA 13 (IP54) protection, and programmable decimal points.
