Features:
- Intrinsically Safe Power Distribution
- Flexible Dual-Protocol Communication & Redundancy
- Advanced Asset Management & Comprehensive Diagnostics
The STAHL 9440/15-01-11 efficiently supplies and distributes reliable power to a maximum of 16 IS1+ I/O modules via the internal BusRail. It generates strictly limited intrinsically safe field circuits, allowing direct connection to field devices located in Zone 1 or Zone 2 hazardous areas without requiring cumbersome external barriers.
Equipped with high-speed RS-485 interfaces, the STAHL 9440/15-01-11 seamlessly supports PROFIBUS DP (V0/V1 with HART) or Modbus RTU communication protocols. Its native architecture fully supports system-level controller redundancy and optical communication ring topologies, ensuring zero downtime and high data availability in mission-critical process loops.
Integrating effortlessly into modern plant asset management systems via ServiceBus and FDT/DTM protocols, the STAHL 9440/15-01-11 delivers deep diagnostic visibility. Engineers can continuously monitor module health, communication quality, and internal error states remotely, significantly reducing mean time to repair (MTTR) and operational overhead.
The 9440/15-01-11 STAHL CPU & Power Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
