It operates on a 20-30 VDC sensor supply and draws up to 270 mA total from the AS-i bus. The A/B slave designation means it occupies one of the two addresses available per standard AS-i slave slot, doubling the node count on a single segment. ## M12 pinout and wiring Each of the four M12 sockets carries the same pin assignment: PIN 1 is sensor supply L+, PIN 2 is data input, PIN 3 is sensor supply L-, PIN 4 is data input, and PIN 5 is the ground terminal. The module uses PIN 4/2 as the signal pair — IN1 on socket 1, IN2 on socket 2, IN3 on socket 3, IN4 on socket 4. The ground terminal exits via a flat tab sleeve (2.8 x 0.8 mm, form A) for daisy-chaining the common rail. ## Addressing and status indication Addressing is done through the front addressing socket. The I/O status is shown by a yellow LED per channel, and the AS-Interface diagnostics are indicated by a green/red dual LED.","metaTitle":"Siemens 3RK2200-0CQ20-0AA3 AS-i Compact Module, 4 Inputs","metaDescription":"Siemens 3RK2200-0CQ20-0AA3 AS-Interface compact module K45, 4 digital PNP inputs, IP67, A/B slave, 20-30 VDC.
