The relay outputs are bistable (latching), meaning they hold their state without continuous coil power — useful for fail-safe holding circuits or applications where a power loss must not reset the output position. Supply voltage is 110-240 V AC/DC (50/60 Hz), with a typical active power consumption of just 0.7 W — low thermal load inside the enclosure. ## Contact Ratings and Temperature Derating The relay outputs are rated 6 A at 120 V and 3 A at 230 V, dropping to 5 A at 60 °C ambient — the 50 °C rating is 6 A, so plan the load circuit with the 60 °C ceiling if the panel runs warm. At 24 V DC the contacts are rated 2 A; at 125 V DC the rating drops to 0.25 A — the DC switching limit is significantly lower than AC, typical for relay contacts breaking a DC arc. Operating temperature range is -25 to +60 °C, with storage and transport limits of -40 to +80 °C — suitable for most indoor industrial environments without climate control. ## Screw and Snap-On Mounting — Any Position Fastening is by screw and snap-on mounting onto a DIN rail, with any mounting position allowed — no orientation restrictions for airflow or gravity. Dimensions are 92 mm height, 22.5 mm width, 124 mm depth — the 22.5 mm width matches the standard SIRIUS module pitch, so it occupies one slot in a multi-module assembly. Terminals accept 1x (0.5-4.0 mm²) or 2x (0.5-2.5 mm²) solid wire, or 1x (20-14 AWG) or 2x (20-16 AWG) stranded — standard screw-clamp termination for panel wiring.","metaTitle":"Siemens 3UF7310-1AU00-0 SIRIUS Digital Module, 4DI/2DO Relay","metaDescription":"Siemens 3UF7310-1AU00-0 SIRIUS digital module with 4 digital inputs and 2 bistable relay outputs.
