The ABB 1SVR010200R1600 is a CC-E I/I analog signal converter — a loop-powered current isolator that takes a 0-20 mA or 4-20 mA input and passes an isolated copy to the output without needing an external supply. Electrical isolation between input and output breaks ground loops.
Single-channel format means one isolator per analog point — no shared-channel crosstalk to worry about when commissioning a multi-loop skid.
