Product Performance
- Efficient Bus Transfer: Supports full-rate adaptation of PROFIBUS DP bus, enabling high-speed data transmission between modules and the main controller with a data refresh cycle ≤1ms, ensuring the real-time performance of the control system.
- Stable Connection Capacity: Can connect up to 32 extended modules, supports hot swapping of modules, and does not affect bus communication during plugging, improving the convenience and continuity of system maintenance.
- Strong Anti-Interference Design: Optoelectronic isolation (isolation voltage 2500Vrms) is adopted for power supply and signal circuits, effectively resisting electromagnetic interference in industrial environments and ensuring stable signal transmission.
- Wide Environmental Adaptation: Operates stably in the temperature range of -25°C to +60°C, adapting to high and low temperature industrial field environments, and can work reliably without additional temperature control measures.
