The Siemens 3RK1400-1DQ05-0AA3 is a K60 compact digital I/O module for field-mount applications, offering 4 PNP inputs and 4 outputs in an IP67-rated housing. It is approved for use in Zone 22 hazardous areas with non-conductive dust (ATEX II 3D), and carries a shock resistance of 15g per 11 ms. The module requires an external auxiliary supply of 20 to 30 V DC (PELV, protection class III) to power the output circuits. Built-in watchdog, short-circuit protection, and induction protection are included on the module.
Mounts on standard rail or wall-mounted using the K60 compact module mounting plate; delivered without the plate. Dimensions: 60 mm wide, 152 mm high, 29 mm deep — fits in tight field junction boxes or small sub-panels. Eight M12 sockets carry the I/O wiring; pin assignments are fixed per socket for inputs (sockets 1-4) and outputs (sockets 5-8). Addressing is set via a front addressing socket; the ID/ID2 code is F/F.
