It provides 4 digital inputs (PNP transistor, 20–30 V supply) and 4 relay changeover outputs, each rated for AC-15 duty at 3 A / 230 V — enough to switch small contactors, signal lamps, or solenoid valves without an interposing relay. The AC-15 rating of 3 A at 230 V / 50–60 Hz tells you the relay outputs are tested for inductive switching (typical for contactor coils and small motors), not just resistive loads. Each output is a floating changeover relay, so you can wire normally-open or normally-closed without external jumpers. The 4 inputs are PNP-sourcing, standard for Siemens and most European PLC families — verify your sensor common is 24 VDC, not 0 V. The module draws its power from the AS-Interface bus (20–30 VDC), and the built-in watchdog monitors communication. If the AS-i master stops talking, the outputs go to a safe state. The front addressing socket lets you set the slave address without pulling the module off the rail — useful when commissioning a line where every slot is already wired. At 45 mm wide and 106 mm tall, this module fits the SlimLine S22.5 footprint — one of the narrowest AS-i I/O slices on the market. The spring-cage terminals accept 1 x (0.5–4) mm² solid or 2 x (0.5–2.5) mm² stranded; with end sleeves, 1 x (0.5–2.5) mm² or 2 x (0.5–1.5) mm². An external 6 A gL/gG fuse protects each output group against short circuits. IP20 means it stays inside the cabinet — no washdown rating.","metaTitle":"Siemens 3RK1402-3CE00-0AA2 AS-i SlimLine I/O, 4IN/4OUT relay","metaDescription":"Siemens 3RK1402-3CE00-0AA2 AS-Interface SlimLine S22.5 I/O module, 4 digital inputs (PNP) and 4 relay changeover outputs, IP20, current production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"D0":"IN1/OUT1","D1":"IN2 /OUT2","D2":"IN3/OUT3","D3":"IN4/OUT4","Type":"4 inputs / 4 outputs","Depth":"86mm","FAULT":"red LED","Solid":"1 x (0.5 - 4) mm² or 2 x (0.5 - 2.5) mm²","Width":"45mm","title":"3RK1402-3CE00-0AA2","Height":"106mm","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!!!
