The Eastron DCM230 is a DIN rail DC energy meter designed for measuring and monitoring in DC systems. It can measure important DC parameters such as voltage, current, power, and energy. The meter supports bi-directional measurement with pulse output and all data is accessible via RS485 using Modbus RTU. The DCM230 is available in two versions, working with either AC or DC power supply. It offers a wide input voltage range up to 300V, 600V, or 1000V DC, and flexible current inputs with DC shunt and current sensors. A multi-tariff version is available, equipped with a Real-Time Clock (RTC) to provide multi-tariff information and monthly records.
The DCM230 measures and displays various DC parameters including voltage, currents, power, and active energy (imported and exported). It provides a pulse output to indicate real-time energy measurement. The RS485 output enables remote monitoring via another display or a computer. An over-current alarm feature is included, which activates an LED and updates a register value when the current exceeds the set CT1 value, allowing users to detect overcurrent conditions through communication. The pulse output is a passive type, compliant with IEC62053-31 Class A.
The unit can be configured for primary current from 0-2000A with a secondary input of 75mV (default), 45mV, or 60mV (optional).
The DCM230 features a user-friendly interface with two buttons on the front panel for navigation and configuration.
