The ABB 1SVR011718R2500 is a single-function CC-E I/I signal converter that takes a 4-20 mA input and reproduces it as a 4-20 mA output, isolated and conditioned for the control loop. It's the kind of part you spec when you need to break a ground loop, shift the signal reference, or protect a PLC analog input card from a field transmitter that's seen better days. Response time is 200 µs — fast enough for most process signals (pressure, flow, level) but not for high-speed motion control. The ±0.5 % of full-scale accuracy means at 20 mA you're within 0.1 mA of the true value; for a 0-100 bar transmitter that's ±0.5 bar. That's standard for this class; if your loop needs better than 0.1 %, you're looking at a different tier of transmitter, not the isolator.
The ambient temperature range is 0...+60 °C operating, -20...+80 °C storage. That covers most indoor panel environments; if your cabinet sits next to a furnace or in a freezer warehouse, watch the operating ceiling.
