Product Introduction
The SDCS‑FEP‑1 (3BSE006309R0001) is a field‑protection and fault‑trigger module designed for ABB’s DCS (Drive Control System) series. This board functions as an over‑voltage and fault protection interface within high‑voltage drive control systems. Specifically, the FEP‑1 variant is suited for systems with line voltages up to 500 V (IEC) and is equipped with a 1,400 V trigger diode for fault detection and tripping.
The module is intended for installation in the power‑electronics domain of a drive control rack where protection of converters, field exciters, or DC drives is critical. It monitors system‑line conditions, triggers protection relays upon over‑voltage or transient events, and works in conjunction with main drive modules to safeguard the drive train.
Built with rugged industrial components and designed for integration with modular DCS drive systems, the SDCS‑FEP‑1 supports reliability, fast fault response, and reduced downtime in heavy‑duty industrial automation applications.

Applications
The SDCS‑FEP‑1 board is used in industrial applications that require robust fault and over‑voltage protection within drive systems. Typical application scenarios include:
-
Large DC or AC‑drives in heavy industry (steel mills, rolling mills) where the protection board monitors line voltage and triggers in event of fault.
-
Field exciter control for synchronous machines in power‑generation plants, where the FEP module safeguards excitation power supply and drive interface.
-
Modular drive racks in automation plants that include redundant fault‑protection modules to ensure high system availability.
-
Marine propulsion and offshore auxiliary drives where robust protection and fast fault isolation are required under harsh environmental conditions.
-
Retrofit or upgrade installations of legacy DCS systems, where adding a modern protection board can improve reliability and maintenance response.
In all these environments the SDCS‑FEP‑1 offers fast fault detection, robust protection, minimal system interruption and enhanced drive system safety.
Advantages
-
Dedicated Drive‑Protection Design: Built specifically for drive systems with over‑voltage and fault‑trigger capability, tailored for drive racks rather than generic modules.
-
Fast Response & Fault Isolation: Equipped with a high‑voltage trigger diode (1,400 V) and designed for rapid fault detection to limit damage to converters and field circuits.
-
Compact and Lightweight Board: The board itself occupies modest space in the rack, simplifying installation and service access.
-
Modular Integration: Designed for plug‑in or rack‑mount placement within ABB DCS systems, making upgrade and replacement simpler.
-
High Reliability Components: Industrial‑grade construction ensures stability in harsh environments, reducing unscheduled downtime.
-
System Compatibility: Fully compatible with ABB DCS series modular racks, facilitate consistent maintenance and spare‑parts strategy.
-
Reduced Maintenance Overhead: By detecting and isolating faults early, the board contributes to lower lifecycle cost and improved uptime.
-
Enhanced Safety & Protection: Ensures critical drive modules are safeguarded — important in heavy industrial operations where drive failure is costly.
