SPBRC410 ABB Controller With Modbus TCP Interface DCS Card Components 256 MHz

Product Overview

The ABB SPBRC410 is a high-performance bridge controller in the Symphony™ Plus DCS family. It integrates a built-in MCF5475 32-bit processor (256 MHz), combining data acquisition, algorithm execution, signal output, and protocol conversion. It can complete master/slave switching within 10 ms, providing zero-interruption control for continuous production scenarios in power, petrochemical, and metallurgical industries.

Key Selling Points

- **Redundant Brain**: Supports 1:1 hot-swappable redundancy, ensuring smooth fault switching and system availability >99.99%.

- **Universal Interfaces**: 1×10/100M Ethernet (Modbus TCP), 2×RS-232, RS-485/CAN optional, compatible with Harmony/S800 I/O and INFI 90® OPEN legacy systems, protecting existing investments.

- **Extremely Rugged:** Industrial-grade wide temperature range of -25℃ to +70℃, IP20 (upgradeable to IP65) protection, resistant to 4g vibration and ±4kV surge, direct installation in field racks.

- **High-Speed ​​Computing:** 64 MB RAM + 4 MB ROM, built-in 2 MB power-down retainable NVRAM, cycle time ≤ 1 ms, meeting the integrated needs of high-speed process control and motion control.

- **Energy-Saving:** Typical power consumption of only 5.25 W, saving 30% energy compared to traditional PLC racks, supports sleep/wake-up mode, contributing to carbon reduction.
