The Siemens 3RK2200-0DQ00-0AA3 is a K60 compact digital input module designed for field-mounting at IP67. It provides 8 PNP inputs (6 mA minimum signal current) and operates on a 20-30 VDC sensor supply. The module is an A/B slave on PROFIBUS and requires two consecutive addresses — this is the key addressing constraint to plan for during configuration.
Mounts on standard DIN rail or via the K60 mounting plate for wall mounting. Dimensions are 60 mm wide, 152 mm high, 29 mm deep — fits a compact footprint in the field junction box. Each of the 8 M12 sockets maps two input channels per socket (PIN 4 = data input I, PIN 2 = data input II), with PIN 5 serving as a common ground terminal bonded to the mounting plate's grounding wrist strap. Delivered without the mounting plate.
