3RK1304-0FS01-0AA3 — Siemens SIRIUS AS-Interface Master Module
Siemens AS-Interface (AS-i) is a sensor/actuator fieldbus system that connects up to 62 binary slaves or 31 analog slaves using a single unshielded two-wire flat yellow cable that simultaneously carries both data communications and 24 V DC power to all connected devices. The S7-1200/1500 AS-i master module connects the AS-i network to the PLC's PROFINET backplane, enabling simple field-device networking for binary sensors, solenoid valves, motor starters, indicator lights, and pushbutton boxes with minimal wiring investment compared to traditional star-wired I/O cabinets.
The AS-i V3.0 protocol supports both standard binary slaves and the AS-i Safety at Work (SaW) protocol for safe inputs (SIL 3 / Cat. 4 / PLe) on the same cable — allowing emergency stop pushbuttons, safety light curtains, and safety mat contacts to be connected as AS-i safe slaves alongside standard field devices without a dedicated safety bus. Maximum cable distance of 100 m per segment (extending to 300 m with repeaters) covers most machine and conveyor cell geometries. The AS-i flat cable's tool-insulation-displacement (IDC) connection to slaves eliminates cable stripping and terminal crimping, making AS-i the fastest-to-install fieldbus for sensor-dense applications.
In Saudi Arabia, AS-i KSA is widely used in automated material handling systems, packaging machine sensor buses, and conveyor system I/O networking where large numbers of binary sensors and actuators must be connected economically over long runs. SABIC and Aramco packaging automation facilities in Jubail, food processing conveyor lines in MODON Riyadh, and airport ground handling equipment at Saudi airports use AS-i to connect position sensors, photoelectric barriers, proximity switches, and solenoid valves without the panel size and wiring cost of conventional I/O marshalling cabinets. The AS-i Safety at Work protocol's SIL 3 capability is increasingly exploited in Saudi machine safety applications where E-stop and safety gate switches on AS-i safe slaves reduce safety relay wiring to a single bus cable.
Razz Middle East supplies AS-i masters, power supplies, slaves, flat cables, and IDC accessories, providing complete AS-i network design and commissioning support for Saudi automation projects.

Key Features & Benefits
- Up to 62 slaves on a single unshielded two-wire cable with simultaneous power and data reduces field wiring cost by up to 70% compared to conventional star-wired binary I/O cabinets for sensor-dense conveyor and machine applications.
- AS-i Safety at Work protocol supports SIL 3 / Cat. 4 / PLe safe inputs (emergency stops, safety light curtain OSSD signals, safety mat contacts) on the same cable as standard field devices, eliminating dedicated safety fieldbus infrastructure.
- Tool-free IDC connection to the flat AS-i cable at any point along the run eliminates cable stripping and terminal crimping, reducing slave installation time to under 2 minutes per device in the field.
- 100 m cable distance per segment (extendable to 300 m with AS-i repeaters) covers the majority of conveyor cell and machine building dimensions without additional wiring infrastructure.
- PROFINET and PROFIBUS master interfaces allow AS-i to be integrated into both S7-1500 TIA Portal and legacy S7-300/400 STEP 7 PROFIBUS automation architectures from a single AS-i master hardware variant.
- Mixed standard and safe slaves on the same cable allows a single AS-i network to serve both non-safety field devices (photoelectric sensors, solenoids) and safety devices (E-stops, safety gates) without segregating the bus.
- AS-i V3.0 analog slaves support 4–20 mA, 0–10 V, and thermocouple inputs over the AS-i cable, eliminating individual analog signal cable runs for distributed temperature and level measurement points on long conveyor and process lines.
Industrial Applications in Saudi Arabia
- Conveyor system sensor networking at automated warehouse and logistics facilities in Saudi Arabia, where AS-i connects hundreds of photoelectric sensors, proximity switches, and diverter solenoids without individual wiring from a central I/O cabinet.
- Packaging machine sensor bus at Saudi food and FMCG manufacturers in MODON industrial estates, where AS-i reduces machine cabinet width by replacing 40-plus individual sensor cable entries with a single flat cable entry.
- Airport ground handling equipment sensor networking at Saudi international airports, where AS-i connects baggage conveyor sensors, gate indicators, and interlocks across long baggage handling areas without cable trunking infrastructure.
- SABIC and Aramco filling and packaging line automation at Jubail facilities, where AS-i Safety at Work connects E-stop stations and safety gates along 200+ metre production lines via a single cable run.
- Water treatment plant valve and level sensor networking at NWC treatment works, where AS-i connects open/close limit switches on distribution valves and float switches on process tanks economically over long pipe gallery distances.
- Cement plant conveyor safety networking at Saudi Cement and YACCO sites, where AS-i Safety at Work E-stops on pull-wire switches along multi-hundred-metre conveyor runs replace individual hardwired safety relay circuits.
- Cold storage and food distribution centre automation where AS-i connects door limit switches, temperature sensors, and access control devices across refrigerated warehouse facilities operating at -25°C to +5°C ambient conditions.
