Description
Each DSCL21 loop powered isolator provides a single channel of analog
signal protection by electrically isolating its input from output for any DC process
signal in the range of 0-20mA (or 4-20mA). The DSCL21 operates passively,
obtaining its power from the transmitted signal (see Figure 1).
The input signal is chopped by a proprietary DC chopper circuit, isolation is
provided by transformer coupling, a proprietary technique is used to suppress
transmission of common mode spikes or surges, the output signal from the
secondary of the transformer is reconstructed to the original input signal.
