The ABB 1SVR040010R0000 is a CC-U/STDR Universal signal converter that accepts a wide range of analog inputs — 0…20 mA, 4…20 mA, 0…1 V, 1…5 V, 0…10 V, or ±10 V — and converts them to a relay output via 2 c/o (SPDT) contacts. It runs on a 24-48 V DC supply and responds within 10 ms, making it suitable for monitoring or threshold-switching tasks in a control panel.
The input flexibility (six ranges including 0–20 mA, 4–20 mA, 0–10 V, and ±10 V) means this single unit can replace several dedicated converters in a panel — handy for a legacy line that mixes transmitter types. The 2 c/o SPDT output gives two independent switching channels, each rated for the load in your control circuit (verify coil/contact ratings against your specific load). Response time of 10 ms is fast enough for most process alarms but not for high-speed safety interlocks — treat it as a threshold monitor, not a guard. Rated for 24-48 V DC supply, so it fits standard industrial control voltages without an extra converter.
Ambient temperature range of -20…+60 °C operating and -40…+80 °C storage covers most indoor panel environments; no special derating needed for typical plant-floor conditions.
