Its safe state is defined as the safety outputs switched off, meaning the module drops the relay when a guard opens or a fault is detected, bringing the hazardous motion to a stop. ## Rated Voltage and Input Power The module operates on a rated supply voltage of 110 to 240 VAC at 50 or 60 Hz, making it compatible with standard industrial control panels across global sites. At 24 V the relay contacts are rated 4 A; at 120 V they handle 3 A, and at 240 V the switching capacity drops to 0.5 ms — the contact rating is derated with voltage, so verify the load current at your line voltage. ## Mounting and Environmental Fit The module mounts via screw and snap-on onto a DIN rail, occupying a 45 mm wide footprint with a height of 106 mm and depth of 124 mm — standard for a safety relay in a crowded panel. It operates from -25 to +60 °C and stores from -40 to +80 °C, so it runs cold and stays cold in an unheated enclosure near a freezer line or outdoor installation. ## Wiring and Termination Terminals accept solid wire from 0.5 to 4.0 mm² for a single conductor, or 2x 0.5 to 2.5 mm² for two conductors — enough for daisy-chaining safety contacts without a separate terminal block. The module includes a start input, feedback input, and automatic start capability, so you can wire external reset buttons and monitor contactor feedback directly without extra hardware.","metaTitle":"Siemens 3UF7320-1AU00-0 Safety Switch, 110-240 VAC, 5 Inputs","metaDescription":"Siemens 3UF7320-1AU00-0 safety switch module, 5 digital inputs, relay output, 110-240 VAC rated.
