Introduction
Eastron DCM230 series DC energy meters are designed for measuring and monitoring in DC systems. The din rail DC
energy meters can measure of important DC parameters: Village,. current, power and energy etc. It also support bi-
directional measurement with pulse output. All data in the meter are accessible via RS485 using Modbus RTU. The
meter has two versions working with AC or DC power supply. Input voltage range up to 300, 600, 1000V DC, and
current inputs are flexible with DC shunt and current sensors. The multi-tariff version has a RTC equipped inside, it
can provides multi-tariff information and monthly records.

Shunt Primary Current
The unit can be configured to operate with primary current and secondary input.
Primary current range: 0~2000A.
Second input: 75mV in default (45mV, 60mV optional)
RS485 Output for Modbus RTU
For Modbus RTU, the following RS485 communication parameters can be configured from the Set-up menu:
Baud rate 1200,2400, 4800, 9600,19200 bps
Parity none (default)/odd/even
Stop bits 1 or 2
RS485 network address nnn – 3-digit number, 001 to 247
Modbus™ Word order
Hi/Lo byte order is set automatically to normal or reverse. It cannot be configured from the set-up menu.
Set-up screens are provided for setting up the RS485 port.
Pulse output
The unit provides a pulse output. The constant can be configured to below:
1000 imp/kwh
100 imp/kWh
10 imp/kWh
1 imp/kWh
Pulse width: 200/100(default)/60 ms.

*Over-current alarm: Alarm will happened when the current is over the CT1 value set on the meter. The Alarm LED
will stay solid and the corresponding register value will be changed. The user can read this register through
communication to determine whether an overcurrent alarm has occurred.
The pulse outputs can be set to generate pulses to represent Import kWh/ Export kWh/ total kWh.
The pulse output is passive type, complies with IEC62053-31 Class A.
