The DSCL21-01 is a loop-powered, DIN-mount analog signal isolator that converts a 0-20mA or 4-20mA input signal to a matching isolated output, powered solely by the input loop. It provides 500Vrms isolation, operates with a maximum compliance voltage of 17V, and supports load resistances from 0 to 600Ω. The device has a narrow 12.5mm width, fits EN50022 and EN50035 DIN rails, and operates from -20°C to +65°C. Accuracy is ±0.1% span typical (±0.2% max), with a bandwidth of 750Hz and response time of 1ms to 90% span. It complies with EN50081-2 and EN50082-2 emissions and immunity standards. The housing is Lexan 940 (UL 94 V-0), weighs approximately 35g, and requires no external power or maintenance.
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.
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.
