It reads 2-, 3-, or 4-wire sensors through M12 screw-type connectors, so it handles everything from a simple pressure transmitter to a precision LVDT. The IP67 rating means you mount this directly on the machine or conveyor, not back in a cabinet; the module body and the M12 connections survive washdown and dust without an extra enclosure. ## Power and loop budget The module draws its operating power from the AS-Interface yellow cable — max 160 mA at 30 V from the profile conductors. If you need to power external sensors, you bring a separate 24...30 V auxiliary supply (Uaux) on the black cable; the module can pass through up to 500 mA from that supply to the sensors. Running sensors off the aux bus instead of the AS-i bus keeps the communication loop clean and avoids pulling down the yellow cable voltage below the 26.5 V minimum. The K60 module measures 60 mm wide, 152 mm tall, and 29 mm deep — it clips onto standard DIN rail or mounts to a wall using the separate mounting plate (3RK1901-0CA00, ordered separately). The M12 inputs are on the bottom face, so plan for cable entry clearance below the module. The AS-i connection comes through the standard piercing profile cable or an M12 flat-cable tap. No fieldbus gateway is needed beyond the AS-i master; the module presents as an analog slave with ID code 3 and I/O configuration 7. ## Status LEDs and fault finding Three LEDs on the face tell you the state at a glance: green for AS-Interface communication, green for auxiliary power present, and red for a fault condition. If the red FAULT LED lights, check the sensor wiring or the 24 V aux supply first — the module has a configurable smoothing function that can mask intermittent signal glitches, so a steady fault LED usually points to a hard open or short on the input pair.","metaTitle":"Siemens 3RK1207-2BQ40-0AA3 K60 Analog Input Module, 2 AI, IP","metaDescription":"Siemens 3RK1207-2BQ40-0AA3 AS-Interface compact module K60 analog. 2 analog inputs for voltage (+/-10 V, 1-5 V), IP67, M12 connections.
