Interfaces for External Monitoring
Three interfaces are provided:
One fixed pulse output 3200 Imp/kWh
M-bus parameters are configured through the Set-up screens.
Pulse Relay Output
The pulse relay output can be set to generate pulses to represent kWh or kVArh.
Rate can be set to generate 1 pulse per:
0.01 = 10 Wh/VArh
0.1 = 100 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh
Pulse width 200/100/60 ms.
Relay Rating 240V ac 50mA
For M-bus the parameters can be configured from the
Baud rate 2400, 4800, ,9600, ,19200, 38400
Stop bits 1 or 2
Address 001 to 250
