Proper electrical isolation should be of the highest priority in process control systems.
Used correctly isolation will prevent unwanted current loops, ground loops, damage to delicate equipment and ensure the safety of human operators when high common mode voltages are to be expected.
APCS Signal Isolators provide galvanic isolation between input and output signals as well as converter function to change signal type. Refer to Signal Isolators and Converters as well as Transmitters and Transducers for more detailed information on the APCS signal isolator range.
For more detailed
information on signal isolation see APCS knowledge article KN10012.
