The ABB 1SVR040001R0400 is a CC-U/STD universal signal converter — a DIN-rail mounted analog signal conditioner that takes a wide range of field inputs and outputs a proportional, isolated signal for your PLC or DCS analog input card. Accuracy is rated at ±0.1 % of full-scale — that means a 0–10 V input is reproduced at the output within 10 mV of the true value, tight enough for most process measurements but not for custody-transfer metering. The input stage accepts ±0.9 mA to ±55 mA current, ±45 mV to ±11 V voltage, or resistance from 470 Ohm to 1 MOhm, so it handles everything from a 4-20 mA pressure transmitter to a Pt100 RTD (with external excitation) or a potentiometer position feedback. Output is bipolar: 0 to ±55 mA or 0 to ±11 V, configurable to match the analog input card on your controller — no external scaling resistors needed. Response time of 200 µs means it tracks fast process changes — a valve stroke or a pump ramp — without introducing lag that would show up as phase shift in a control loop.
Runs on a 110-240 V AC supply, so it can share the control transformer with contactors and relays — no separate 24 VDC power supply required for the signal conditioner. Dimensions of 12.0 x 2.25 x 10.5 cm (LxWxH) fit a standard single-width DIN-rail footprint; the 2.25 cm width leaves room for a full row of these in a crowded panel.
