Output
Pulse Output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total /import/ export
kWh or kVArh.
The pulse constant can be set to generate 1 pulse per: 0.001/0.01/0.1/1 kWh/kVArh.
Pulse width: 200/100/60ms
Pulse output 2 is non-configurable. It is fixed to total kWh. The constant is 1000imp/kWh.
RS485 output for Modbus RTU
The meter provides a RS485 port for remote communication. Modbus RTU is the protocol applied. For Modbus
RTU, the following RS485 communication parameters can be configured by the Modbus command.
Baud rate: 1200, 2400, 4800, 9600 bps. Default: 2400 bps
Parity: NONE/EVEN/ODD
Stop bits:1 or 2
Modbus Address: 1 to 247
