22.5 mm wide SIRIUS module — 4 DI, 2 relay DO
The Siemens 3UF7600-1AU01-0 is a SIRIUS multifunction module packing 4 digital inputs and 2 relay outputs into a 22.5 mm wide housing — a common slot width on a DIN-rail panel, so it fits without crowding adjacent devices. Rated supply voltage is 110... 240 V, and the relay outputs are monostable — they drop out on power loss, which is the expected behavior for a safety-related or controlled stop in a motor control center.
Output current ratings across the temperature band
The relay outputs carry 6 A at 50 °C and derate to 5 A at 60 °C — the 1 A drop over that 10 °C rise means the module can still switch a small contactor coil or pilot light inside a warm enclosure without losing margin. At 230 V the contacts are rated 3 A; at 120 V they handle 6 A — the lower current at higher voltage reflects the arc-quenching limit of the relay, so stay within the 3 A ceiling when switching a 230 V load.
IP20 and mounting flexibility
IP20 protection means the module is dust-protected but not sealed against moisture — it belongs inside a cabinet, not on the wet side of a washdown zone. Any mounting position is allowed, which simplifies layout in a crowded panel. Operating temperature range is -25 to +60 °C, with storage and transport down to -40 °C — typical for a control-panel device in a heated plant environment.
