Transmissor AC / DC
Transmissor AC / DC
Principais características

Input galvanically separated from output and supply
AC current measurement
AC voltage measurement
Current and voltage output
24 VDC supply or universally supplied
Applicable in PELV/SELV circuits


±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.

AC current measurement e.g. in connection with a current transformer or a current clamp.
Direct AC voltage measurement.


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.
