The Siemens 3RG9001-0AL00 is an AS-Interface digital output module with 4 PNP transistor outputs, each rated 1 A (DC-12/13), with a 2 A aggregate current limit across all channels. Rated IP67, it is designed for direct field mounting on standard rail or wall via the coupling module — suited for washdown zones or outdoor cabinetless installations on conveyors, packaging lines, or material handling systems. Communication runs on the AS-Interface protocol (V3.0 compatible), with the module drawing up to 60 mA from the AS-i bus; the output power comes from a separate external 20–30 V DC PELV supply (AUX POWER) connected via an M12 connector.
Dimensions: 45 mm wide, 90 mm high, 27 mm deep — fits standard AS-Interface field module footprints, with four M12 sockets for outputs D0–D3. Outputs are short-circuit-proof with built-in induction protection; each channel has a yellow LED status indicator, and the AS-i bus health is shown by a green LED. The module requires an external 20–30 V DC PELV supply (AUX POWER) for the output circuits — do not rely on bus power alone for the loads.
