Each input is PNP transistor type, 20-30 VDC, with a signal-1 minimum of 5 mA and signal-0 maximum of 1.5 mA — typical for standard 3-wire sensors. The outputs are solid-state, delivering 22-24 VDC at 24 V nominal, with a 4 A aggregate current ceiling across all four channels. Critical for panel wiring: an external auxiliary supply (AUX POWER) of 20-30 VDC is required to power the output circuits, and it must comply with VDE 0106 (PELV), protection class III — that's a separate feed, not drawn from the AS-i bus. The module carries built-in short-circuit protection and induction protection, plus a watchdog that monitors bus communication. Status is visible via green AS-Interface LED, yellow I/O LEDs per channel, and a red fault LED. ## Mounting and connection Fastens onto 35 mm standard DIN rail or wall-mounts using the push-in lugs. Spring-loaded terminals accept 2 x (0.25-1.5) mm² solid or stranded, or 2 x (0.25-1) mm² with end sleeves; AWG 24-16 solid or stranded. A detachment tool for the spring terminals is listed under accessories. IP20 protection — intended for clean, dry cabinet environments, not washdown or outdoor locations.","metaTitle":"Siemens 3RK1400-1CG00-0AA2 AS-i SlimLine S22.5, 4I/4O","metaDescription":"Siemens 3RK1400-1CG00-0AA2 AS-Interface standard slave, 4 digital inputs / 4 digital outputs, SlimLine S22.5, IP20, current lifecycle.
