It is a standard slave on the AS-i network, drawing 8 to 12 mA from the bus for its own electronics. Inputs are 2-conductor DC, accepting 26.5 to 31.6 V, with a minimum signal-1 current of 6 mA per channel. The relay outputs switch up to 3 A in AC-15 duty (230 V AC) or 0.1 A in DC-13 at 220 V — the aggregate thermal current Ith is 3 A. Wiring uses spring-loaded terminals for I/O (0.8 to 2.5 mm² flexible without end sleeves) and insulation displacement for the AS-i and auxiliary power connection (0.5 to 0.75 mm² flexible). The module snaps onto standard DIN rail and is IP20 rated. ## Lifecycle Status — Phased Out, Sourced to Order No official successor order code is listed by Siemens for this module. For BOM continuity, a functional cross-reference to a current AS-i load feeder may be needed — confirm fit with the panel layout and AS-i master compatibility before specifying a replacement. ## Integration Notes — Panel Fit and Addressing The module is 45 mm wide and mounts on standard DIN rail. It uses the AS-i bus for communication and auxiliary power via a 5-pole connector (0.5 to 2.5 mm², AWG 28 to 12). The built-in watchdog monitors bus communication; the module retains its last address after the 15th addressing procedure. Status LEDs on the front indicate output activation, AS-i communication OK, communication fault, and station address = 0 (module not addressed). The ID code is F. Operating temperature range is 0 to 55 °C; storage range is -40 to +85 °C. The relay outputs are not short-circuit proof and have no built-in short-circuit protection — external fusing or a protective device must be added per the load circuit. Polarity reversal protection is also not required per the design.","metaTitle":"Siemens 3RK1402-3LG02-0AA1 AS-i Load Feeder","metaDescription":"Siemens 3RK1402-3LG02-0AA1 AS-i load feeder module, 3 inputs / 2 relay outputs, 45 mm width, IP20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Type":"3 inputs / 2 relay outputs","Width":"45mm","title":"3RK1402-3LG02-0AA1","ID code":"F","Watchdog":"built-in","Addressing":"the module retains the last address after the 15th addressing procedure","description":"AS-i load feeder module Phased-out product!!!
