- Accurate measurement of active and reactive energy in three-phase networks
- Direct communication via RS485 Modbus interface
- Easy integration into FENECON Energy Management Systems (FEMS)
- Flexible application for generators, consumers, and grid connection points
- Compact design for DIN rail installation
- High measurement reliability through external current transformer connection
The FENECON FEMS Package 3-Phase Sensor without current transformer is based on the SOCOMEC DIRIS A-10 and is designed for precise measurement of electrical parameters in PV and energy storage systems. The sensor records active and reactive energy in three-phase networks and transmits measurement data via Modbus RS485 directly to the FENECON Energy Management System (FEMS), enabling efficient monitoring and control of energy flows between generators, consumers, and grid connection points.
Features & Installation Notes
The SOCOMEC DIRIS A-10 is a modular energy meter for three-phase systems that operates with external current transformers and ensures reliable data communication via RS485. Voltage supply is connected through all three phases (L1, L2, L3) and the neutral line, supplemented by an auxiliary supply at terminals 20 and 22 (Aux-Supply).
For installation, use a measuring cable with a cross-section of at least 2.5 mm² (up to 3 m cable length) or 4 mm² (up to 5 m). The unit mounts directly onto a DIN rail in the control cabinet. It can be connected to inverters, metering points, or loads, ensuring correct transformer alignment from K to L.
Communication is provided via a serial RS485 connection (2- or 3-wire), supporting up to 32 devices over distances of up to 1200 meters. A 120 Ω termination resistor is required for stable signal transmission. The standard baud rate is 9.6, and Modbus addresses are configured according to FEMS integration requirements.
