Siemens 3RK2200-0CE02-0AA2 Interface Module

Siemens 3RK2200-0CE02-0AA2 Interface Module is a SlimLine AS-Interface input interface that adds four digital inputs to an AS‑Interface network and operates as a slave on the two‑wire AS‑i bus. The 0CE02 variant specifies four DI with an A/B address, part of the 3RK2200 family of SlimLine control cabinet modules; the 0AA2 suffix denotes the shipment/assembly code. This module is designed for use in Siemens automation environments that use SlimLine Compact configurations (S22.5, S22.5F, and S45 SlimLine Compact), enabling reliable, time‑synchronous reading of discrete sensors by a compatible PLC or controller. Each of the four channels supports standard digital input signals, and the module presents its input states to the AS‑Interface master according to the assigned A/B address. Typical applications include remote input sensing in machine control panels, such as door sensors, start/stop buttons, and limit switches, where compact, plug‑and‑play I/O expansion on the AS‑Interface network is required. The part is explicitly listed as an AS‑Interface input slave module, reinforcing its role as a simple, reliable interface block within Siemens’ industrial automation ecosystem.
