It provides 2 digital inputs (PNP transistor circuit, 20-30 VDC supply) and 2 digital outputs via relay changeover contacts, floating. The module is addressed through a front addressing socket; ID/ID2 code is 0/F. A built-in watchdog monitors communication, and the AS-Interface green LED confirms bus health. Input voltage range is 20-30 VDC. The 2 inputs are PNP only — ensure your sensors source positive to the module; NPN sensors need an interface. The relay outputs are changeover floating contacts rated 1 A at 24 V, 0.2 A at 110 V, and 0.1 A at 230 V, so they suit signal-level switching or low-power loads, not motor contactor coils directly. The module requires an external 6 A gL/gG backup fuse for short-circuit protection. With IP20 protection, it belongs inside an enclosure, not on the machine frame. Wiring uses 2-wire technology with spring-loaded terminals accepting 2 x (0.25-1.5) mm² solid or 2 x (0.25-1) mm² with end sleeve; AWG 24-16 stranded. A detachment tool is listed as an accessory. Status indication: yellow LEDs for I/O states, red LED for fault, green for AS-Interface bus.","metaTitle":"Siemens 3RK1402-0BG00-0AA2 AS-Interface SlimLine, 2I/2O rela","metaDescription":"Siemens 3RK1402-0BG00-0AA2 AS-Interface standard slave, 2 digital inputs (PNP) and 2 relay changeover outputs, SlimLine S22.5, IP20, 20-30 VDC, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"D0":"IN1","D1":"IN2","D2":"OUT1","D3":"OUT2","Type":"2 inputs / 2 outputs","Depth":"86mm","FAULT":"red LED","Solid":"2 x (0.25 - 1.5) mm²","Width":"22.5mm","title":"3RK1402-0BG00-0AA2","Height":"103mm","Note 1":"detachment tool for spring-loaded terminal connection: See Accessories","at 24 V":"1A","Watchdog":"built-in","at 110 V":"0.2A","at 230 V":"0.1A","Addressing":"front addressing socket","ID/ID2 code":"0/F","description":"AS-i SlimLine module Phased-out product!!!
