The module draws its logic power from the AS-Interface bus, but an external auxiliary supply of 20 to 30 V DC (PELV per VDE 0106) is required to power the output circuits. Aggregate output current is capped at 4 A total across both channels. Inputs are PNP transistor type with a switching threshold of 10 V minimum for a High signal and a maximum 1.5 mA leakage at Low. This means the module expects sourcing (PNP) sensors — if your panel uses NPN sensors, you will need an interface converter or a different slave. Each input draws a minimum 5 mA at the High level, so verify the sensor can sink that current. Outputs are also PNP transistor type, delivering 22 to 24 V DC at the terminal. The 4 A aggregate maximum is the total across both outputs, not per channel — if one output runs at 3 A, the other is limited to 1 A. Built-in short-circuit and induction protection on the outputs means you do not need external clamping diodes for small inductive loads like relays or solenoid valves. The module occupies 22.5 mm on a 35 mm DIN rail and is 86 mm deep, fitting the SlimLine S22.5 footprint. ## Integration notes Status indication: green LED for AS-Interface communication, yellow LEDs per I/O channel, red LED for fault. The built-in watchdog monitors bus communication and resets outputs if the master stops talking. The module is a standard slave (not an A/B slave), so it occupies one address on the bus.","metaTitle":"3RK1400-0BE00-0AA2 AS-Interface SlimLine S22.5, 2 inputs / 2","metaDescription":"Siemens 3RK1400-0BE00-0AA2 AS-Interface standard slave module, 2 PNP inputs / 2 PNP outputs, 4 A aggregate, IP20, current lifecycle.
