Advanced features
- ±20% adjustment of the 0 and the 100% measurement range is possible at the front panel.
- Input and output ranges are programmable by use of internal DIP-switches.
Application
- AC current measurement e.g. in connection with a current transformer or a current clamp.
- Direct AC voltage measurement.
Technical characteristics
- Analog signal conditioning with microprocessor based gain and zero offset.
- Signals in the ranges 0.5...250 VRMS sinusoidal voltage can be connected directly to the input, ranges are programmed via DIP-switches and jumpers.
- Analog standard current output of 0/4...20 mA or standard voltages of 0...1 or 0...10 VDC ranges are programmed via DIP-switches and jumpers.
- Special currents and voltages within the signal range.
- Signal reversal e.g. 20...4 mA is possible in a special version.
- Universally supplied units have a 3-port galvanic separation between input, supply, and output.
- Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
