Popis
OMEGAs new universal panel meter DP20 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 600 V) and AC and DC ammeter (up to 5 A) offering application flexibility for process control and industrial requirements. A single universal power supply 18 to 265 Vac/dc 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, IP65 protection, and programmable decimal points.
