The module provides galvanic separation of standard current signals 0-20mA, 4-20mA. The power
for supplying the module is obtained from the input measuring signal. The module can be used to isolate a
two-wire converter supplied by a 4-20mA signal. Galvanic separation is achieved by means of a
transformer. The input DC signal is modulated to an AC signal which, after being transferred by the
transformer, is demodulated back to a DC signal. The input circuit is protected against RFI/EMF and against
incorrect polarity. There is a precise DC transformer in operation principle. Therefore is necessary closed
secondary circuit for primary current passing. |
