Product Introduction
ABB REG316 is a fully numerical generator protection relay designed for generator, motor, and unit transformer protection in industrial and utility power systems. The relay belongs to ABB’s RE.316*4 protection family and uses microprocessor-based signal processing for fault detection, event recording, and disturbance analysis.
The system supports IEC 60870-5-103, MVB, and RS232 communication interfaces, making it compatible with older substation control systems and retrofit projects. Its modular hardware design allows flexible binary I/O expansion while reducing spare-part inventory requirements for legacy ABB protection platforms.
Frequently Asked Questions
Q: Does the REG316 support hot-swapping?
A: Honestly, no. The relay was designed before modern hot-swap architectures became common in protection systems. Power down the rack before replacing plug-in units. Pulling modules live can corrupt settings or damage the backplane.
Q: Is the REG316 obsolete?
A: Yes. ABB classifies the RE.316*4 family as a legacy protection platform. Stock availability is becoming inconsistent, especially for specific hardware revisions. Many plants now keep buffer stock because emergency sourcing lead times are unpredictable.
