It features 24-bit A/D conversion, an adjustable sample rate up to 200khz, and five active input channels. It has a built-in digital signal processor (DSP) and includes true RMS, averaging, and peak-holding algorithms. It also provides isolated current and voltage outputs up to 4 shields, and accepts 4-20mA, 0-5V DC, 0-10V DC, and one- or two- wire 4-20mA active signals. It also has a built-in RS-485 serial connection for communication with PLCs and SCADA systems, and a USB interface for access to local displays.
