The Ringway ISOPLC Series of Opto Isolators are designed to allow the isolated monitoring of low voltage AC signals (100-250V) or low voltage DC (24-50V) signals using standard DC PLC inputs. The isolators work by switching their output to the PLC on while an input signal is present. The Isolator output to the PLC may be wired in either a sourcing or sinking arrangement.
