IP67 rated, it mounts on standard rail or wall plate next to the sensors it serves — no enclosure needed. The 270 mA total current budget from the AS-i bus powers the module and the sensor supply on pins 1 and 3, so plan the segment load accordingly. ## Pinout and Addressing Each of the four M12 sockets maps two data pins: pin 4 carries the input signal, pin 2 carries the second channel. Socket 1 uses pins 4/2 for IN1 (D0), socket 2 for IN2 (D1), socket 3 for IN3 (D2), socket 4 for IN4 (D3). Pin 5 on every socket is the ground terminal, routed out through a 2.8 x 0.8 mm flat tab sleeve. The module address is set via the front addressing socket; the ID/ID2 code is 0/F. ## Mounting and Commissioning The module ships without a mounting plate. For wall mounting, order the K45 compact module mounting plate separately. Standard rail mounting uses the integral snap-on foot. The green/red dual LED on the front shows AS-Interface communication and diagnostics; each input channel has a yellow LED for signal state.","metaTitle":"Siemens 3RK1200-0CQ20-0AA3 AS-i Compact Module, 4 PNP Inputs","metaDescription":"Siemens 3RK1200-0CQ20-0AA3 AS-Interface compact module with 4 digital PNP inputs, IP67 protection, K45 housing.
