8 DN Multisignal Panel Meter Economical Panel Meter for Process, Temperature and Electrical Measurement DP20 TM DP20 meter shown smaller than actual size. OME s new multisignal panel meter delivers high-performance in a 8 DN size for panel mounts and integration in a wide range of applications. The DP20 accepts universal inputs, including thermocouple, RTD, process (m & Vdc), resistance, frequency and true RMS voltage and current. y configuration, it will work as an C and DC voltmeter (up to 600 V) and C and DC ammeter (up to 5 ) offering application flexibility for process control and industrial requirements. 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. dditional features of the economical DP20 panel meter include scaling, NEM 3 (P65) protection, and programmable decimal points.
