The Siemens 3RK1005-0LB00-0AA0 is a SIRIUS ET200S interface module that serves as a 4-port IO-Link master for SIRIUS switching technology devices. Each of the four ports supports IO-Link communication at COM2 rate (38.4 kBaud), with a maximum process data size of 8 bytes per port and 32 bytes total across all ports. The module can also operate with IO-Link deactivated, functioning as standard digital I/O. Powered by a 24 VDC supply, it draws a maximum of 0.3 A and includes reverse polarity protection. Each port is short-circuit rated at 0.4 A.
At just 15 mm wide, the module packs four IO-Link master ports into a single slice, saving DIN-rail space in dense ET200S stations. It mounts in any position and clips on without tools. Rated for horizontal operation at 0 to 60°C and vertical at 0 to 50°C, with humidity tolerance of 15 to 95% non-condensing. Shock rated at 15 g for 11 ms, vibration at 0.35 mm / 5 g. Pollution degree 2 per IEC 61131 means it's suited for clean, dry control-room environments. ESD immunity meets 4 kV contact / 8 kV air discharge per IEC 61000-4-2. Insulation voltage rated at 500 V. Maximum installation altitude 2000 m.
