It's designed for mechanical switching contact sensors — think limit switches or emergency stop buttons — and feeds their signals into an AS-Interface safety network. The IP67 rating means this module lives directly on the machine frame, not in a cabinet, so it's suited for washdown zones or dusty environments where a control panel would be impractical. Power comes straight from the AS-Interface cable at 26.5 to 31.5 V DC, and the two standard outputs draw their supply from that same bus — no separate 24 V power feed needed for the outputs. The module draws up to 270 mA from the AS-Interface total current. Each output is rated 0.18 A at signal <1>, solid-state, short-circuit proof. Four M12 sockets handle the connections — the inputs use a special pin assignment (not the standard M12 pinout for sensors), so verify the wiring diagram before terminating. The outputs follow a standard assignment. A front addressing socket lets you set the AS-Interface address without opening the module. Built-in watchdog and short-circuit protection reduce the need for external safety relays in the loop. The compact footprint — 60 mm wide, 29 mm deep, 152 mm tall — fits into tight machine-mounted junction boxes alongside other K60 slices. The IP67 sealing means the electronics are protected against dust ingress and temporary immersion — hosing down the machine at the end of a shift won't kill it. The M12 connectors are the weak point; keep caps on unused sockets and torque to spec to maintain the seal. The two safe inputs are designed for mechanical switching contacts — think dry contacts from an E-stop, a safety gate switch, or a two-hand control. They're not for proximity sensors or light curtains; those need a different input type. The switching level is simple: contact open = low, contact closed = high. Each input draws a minimum of 5 mA at signal <1>, which is enough to wet the contacts and prevent oxidation on low-current mechanical switches. The two standard outputs are solid-state, 0.18 A each, powered from the AS-Interface bus. That's enough for indicator lamps, small solenoid valves, or signal relays — not for direct motor or actuator drive. The short-circuit proof design means you won't blow the output if a field wire gets pinched. The AS-Interface protocol is fixed — this module speaks AS-i, not PROFIBUS or PROFINET. It carries an ID/ID2 code of B/F, which the AS-i master uses to identify it during commissioning. The yellow LEDs on each I/O socket give a quick visual on signal state, and the green/red LED on the AS-Interface connection shows bus health and diagnostics.","metaTitle":"Siemens 3RK1405-0BQ00-0AA3 ASIsafe K60F, 2 F-DI/2 DQ, IP67","metaDescription":"Siemens 3RK1405-0BQ00-0AA3 ASIsafe compact module K60F with 2 safe inputs, 2 standard outputs, IP67.
