Product Overview
The SDCS‑REB‑1 is an interface and routing board for ABB’s DCS drive systems. Its primary role is to route firing pulses from upstream interface boards (e.g., PIN‑51) to downstream thyristor driver boards (e.g., PIN‑48) in both forward and reverse bridge configurations. It ensures timing accuracy, signal integrity, and simplified wiring for large industrial DC drives.
The board is designed to be modular, plug-in, and durable in industrial environments, supporting reliable operations under vibration, temperature fluctuations, and electrical noise. Its compact design fits within the converter electronics stack, making maintenance and replacement straightforward.

Product Description
The SDCS‑REB‑1 board receives firing pulses and direction signals and distributes them to the appropriate thyristor driver boards for forward and reverse motor control. It centralizes pulse routing, which reduces wiring complexity and ensures consistent timing across all bridge circuits.
The modular design allows for quick replacement during maintenance, helping to maintain high uptime in industrial drive systems. By handling both the routing of signals and direction logic, the REB‑1 plays a critical role in safe and reliable motor operation.
