An external auxiliary supply (AUX POWER) of 20 to 30 V DC is required for the output circuits, and must comply with VDE 0106 (PELV), protection class III — the module does not derive output power from the AS-Interface bus alone. ## I/O mapping and diagnostics The four I/O channels are mapped as D0 (IN1/OUT1), D1 (IN2/OUT2), D2 (IN3/OUT3), and D3 (IN4/OUT4). I/O configuration is set to 7, addressing is done via the front addressing socket. Diagnostics are visible through three LEDs: green for AS-Interface communication, yellow per-channel for I/O status, and red for fault indication. A built-in watchdog monitors bus communication. Short-circuit protection and induction protection are both built-in, so external fusing or snubbers on the output side are not required for basic protection. Fastening is via 35 mm standard rail mounting or wall mounting using push-in lugs. Connection technology supports 2- and 3-wire sensors. Solid wire: 1 x (0.5–4) mm² or 2 x (0.5–2.5) mm²; with end sleeve: 1 x (0.5–2.5) mm² or 2 x (0.5–1.5) mm². AWG solid or stranded: 2 x (20–14).","metaTitle":"Siemens 3RK1400-1CE01-0AA2 AS-Interface Slave, 4DI/4DO, IP20","metaDescription":"Siemens 3RK1400-1CE01-0AA2 AS-Interface standard slave with 4 digital inputs (PNP) and 4 solid-state outputs.
