3. Key Features

1. Hybrid‑ABOX design: Combines power, safety, and fieldbus in one IP65 unit; uses M12 connectors for I/O instead of screw terminals for faster assembly.

2. PROFIsafe STO: Integrated safe torque off, meets PL d / SIL 3 for safe drive systems.

3. Profinet (CU): Onboard Profinet interface for controller‑based communication; supports real‑time automation.

4. Decentralized wiring: Reduces control cabinet wiring; ideal for modular machine concepts.

5. Industrial durability: IP65 for wash‑down, food & beverage, logistics, and outdoor installations.

4. Typical Applications

• Decentralized conveyor systems, packaging machines, intralogistics

• Food & beverage, pharmaceutical (wash‑down capable)

• Plant sections requiring Profinet + PROFIsafe safety

• Fan, pump, and general machinery with distributed motors
