The input circuit is PNP, switching at 20...30V, with the module drawing its sensor supply and power from the AS-Interface cable itself. Outputs are solid-state, rated 700mA per channel at 24V DC, with built-in short-circuit protection and a freewheel diode for inductive loads. ## I/O mapping and status at a glance The four I/O channels map as D0=IN1/OUT1, D1=IN2/OUT2, D2=IN3/OUT3, D3=IN4/OUT4. The I/O configuration code is 7, and the ID/ID2 code is 0/F — a standard slave profile. LED status is straightforward: green for AS-i active, red for fault, yellow per channel for input/output state, and a separate green for 24V supply. The LED blink patterns tell you whether you've got healthy traffic, no data, a zero address, or a sensor overload on the bus. ## Power budget and physical fit Total AS-Interface current draw maxes at 270mA, and the combined current for all inputs and outputs is capped at 200mA. Outputs need an external 24V DC supply fed through the printed-circuit board contacts — the module doesn't generate that rail internally. Physically it's a slim profile: 75mm wide, 54mm deep, and only 9mm tall. The IP00 rating means no enclosure protection; this board lives inside a host device or panel, not exposed on the line.","metaTitle":"Siemens 3RK1400-1CD00-0AA2 AS-Interface Module, 4I/4O PNP","metaDescription":"Siemens 3RK1400-1CD00-0AA2 AS-Interface communication module with 4 digital inputs and 4 outputs, PNP input circuit, IP00, current production.
