Item description

Short description:

The Current Signal Conditioner detects alternating and direct currents,

( 0 ... 1 A AC/DC and 0 ... 5 A AC/DC) and converts the input signal into a standard analog signal at the output side.

Features:

PC configuration interface

True RMS measurement or arithmetic mean value

Digital switching output (configurable switching thresholds)

Switchable filter function

Calibrated measurement range switching

Safe 3-way isolation with 2.5 kV test voltage acc. to EN 61140
