Bipolar Isolated DIN Rail Signal Conditioner/Splitter for Process Signals
The DRSL-SP3 bipolar isolated signal conditioner/splitter provides a competitive choice in terms of both price and technology for galvanic isolation of process voltage or current signals to SCADA systems or PLC equipment. Two process outputs are provided which mirror the single process input.
