Why Choose the ABB 1SVR560731R3703 Grid Feeding Monitoring Relay?
The ABB 1SVR560731R3703, also known as the CM-UFD.M34M, is a multifunctional grid feeding monitoring relay with Modbus RTU communication. It is designed to provide interface protection between renewable energy generation systems and the public electricity grid, helping maintain grid stability by continuously monitoring voltage and frequency conditions.
Developed for applications requiring compliance with the DEWA Distributed Renewable Resources Generation standard, the CM-UFD.M34M monitors overvoltage, undervoltage, overfrequency, underfrequency and other critical network conditions. If measured values move outside the permitted limits, the relay signals an external decoupling device to disconnect the generation system safely from the grid.
With a 0–540 V AC phase-to-phase measuring range, a 0–312 V AC phase-to-neutral measuring range and three changeover relay outputs, the CM-UFD.M34M is suitable for commercial photovoltaic systems, distributed generation installations and industrial grid protection panels. Its integrated Modbus RTU interface enables remote access to measurements, operating states and diagnostic information.
Key Advantages
- Multifunctional grid feeding monitoring relay with Modbus RTU.
- Designed for interface protection in accordance with the DEWA DRRG standard.
- Monitors voltage, frequency and grid stability continuously.
- 0–540 V AC phase-to-phase measuring range.

- DIN rail mounting for electrical control panels.
Advanced Grid Protection with Modbus RTU
The ABB CM-UFD.M34M continuously compares measured grid voltage and frequency values with configured protection thresholds. If an abnormal network condition is detected, the relay changes the state of its output contacts and signals an external contactor, switch-disconnector or circuit breaker to isolate the renewable energy system.
Integrated Modbus RTU communication allows measurements, alarms and operating information to be transmitted to compatible PLCs, supervisory systems and energy management platforms. This provides greater system visibility and supports efficient remote diagnostics in modern renewable energy installations.
Typical Applications
- Commercial and industrial photovoltaic installations.
- Distributed renewable energy generation systems.
- Grid-connected solar inverter systems.
- Public-grid interface protection panels.
- Industrial energy management systems.
