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 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 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.
