• Stored energy (EEPROM): max 999.999.999 kWh/kvarh
• Data format: 1 start bit, 8 data bit, no parity/even parity/odd
parity, 1 stop bit
• Baud-rate: 1200, 2400, 4800 and 9600 baud,
• Insulation: by means of optocouplers,
4000 Vrms between output and measuring inputs,
4000 Vrms between output and power supply inputs
RS232 SERIAL OUTPUT (on request):
• Type: bidirectional (static and dynamic variables).
• Connections: 3 wires, maximum distance 15m
• Data format: 1 start bit, 8 data bit, no parity,
1stop bit
• Baud-rate: 9600 bauds
• Protocol: MODBUS (JBUS)
• Other data: as per RS485/RS422
DIGITAL OUTPUTS: (on request)
The working of the outputs (pulse, alarm or both) is fully
programmable and is independent of the output module that
has been chosen.
PULSE OUTPUT: (on request)
• Number of outputs: up to 4 (on request)
• Type: 1 to 1000 programmable pulses for k-M-G Wh, k-M-G
varh, open collector (NPN transistor)
• VON 1.2VDC / max. 100mA; VOFF 30VDC max.
• Pulse duration: 220ms (ON),
≥
220ms (OFF) according to
DIN43864.
• Insulation: by means of optocouplers, 4000 Vrms output to
measuring inputs, 4000 Vrms output to power supply inputs
• Note: the outputs can be either open collector type or relay
type (for this latter one see the characteristics mentioned in
the ALARMS).
