Runs on 24 V DC control power (20.4 to 28.8 V operating range, max 31.6 V) and talks AS-Interface for fieldbus integration. Four digital inputs are built in, addressable via an M12 plug — handy for picking up limit switches or pushbuttons right at the starter without a separate I/O block. The enclosure is IP65, so it's sealed against dust and water jets — fine for washdown areas, outdoor conveyor drives, or any spot where a panel isn't practical. Mount it vertical, horizontal, or flat; screw fixing to the machine frame or a subplate. Dimensions: 294 mm wide, 215 mm tall, 159 mm deep. ## Integration & wiring Main power connects via a HAN Q4/2 plug per ISO 23570 — a standard industrial connector that's quick to mate and strain-relieves the cable. The control and AS-Interface link use M12 connectors; keep the AS-i bus termination at the last device on the line. With a width of 294 mm, it takes up a fair bit of real estate on a subplate. Plan for side clearance if you need to access the M12 plugs or the HAN connector. The screw-fixing pattern is straightforward — four screws into the mounting surface. Vibration resistance is 2g at 7 mm amplitude; shock resistance is 12g for 11 ms — typical for machine-mounted gear near a press or conveyor. ## Timing & protection The starter has a built-in ON-delay of 25 ms and OFF-delay of 35 ms — these are fixed, not adjustable. They prevent contact chatter during fast voltage dips or bus transitions, but don't rely on them for sequenced starting; that's what the AS-Interface network is for.","metaTitle":"Siemens 3RK1315-6NS71-0AA5 SIRIUS Direct Starter, 4 kW 400 V","metaDescription":"Siemens 3RK1315-6NS71-0AA5 SIRIUS direct motor starter, 4 kW at 400 V, CLASS 10, IP65, 24 V DC, AS-Interface, 4 digital inputs.
