DSTC452 5751017-A
Advantages and Characteristics
- Reliable Communication: FSK modulation ensures stable data transmission over long distances (coaxial cables), minimizing interference in noisy industrial settings.
- Easy Integration: Din-rail mountable design for straightforward installation in control cabinets. Compatible with ABB’s S400 and Tyra KL I/O units, as well as third-party systems via serial interfaces.
- Low Power Consumption: Optimized energy usage (<5W typical) for cost-effective operation.
- Durability: Built for harsh environments (wide temperature range, robust construction) with a 1-year warranty.
- Modular Design: Supports flexible configuration for diverse automation needs, including machine control and system management.
Application Areas and Case Studies
- Industries: Manufacturing (e.g., floor board production, ceramic manufacturing), energy (wind turbines, water treatment), infrastructure (tunnel ventilation, ski lifts).
- Case Study: A manufacturing plant upgraded to ABB’s AC 800M system while retaining legacy S400 I/O units. The DSTC452 5751017-A acted as a protocol converter, enabling seamless communication between the new AC 800M and old S400 devices. Result: Reduced downtime, unified control, and cost savings from reusing existing infrastructure.
