- 0-20 mA or 4-20 mA signal transfer in the ratio of 1:1
- energy transfer for powering the two-wire converter
- low voltage drop across the module, typically 3.5V
- designed for DIN 35 rail mounting
- conversion accuracy: < 0.2% |
The module is designed to isolate standard current signals,
0 - 20mA, 4 - 20 mA. The supply power is drawn by the module from the input signal. The module can be used to
isolate a two-wire converter, which is powered via the 4 - 20mA signal line. If a 0 - 20mA signal is to be
isolated, the converter load must be ohmic. The isolation is reached by using a transformer. The input DC signal
is chopped to be converted into an AC signal, which is fed into a transformer. It is picked up from the
transformer secondary winding and subsequently demodulated to produce a DC signal. The input circuit is protected
against noise and polarity reversal. It is also protected against current overload, by means of a resettable
thermal cut-out In principle, it is a high-precision DC current transformer. For the same reason, the secondary
circuit must be closed for the current passage through the primary winding. |
