[3] EXTERNAL INTERFACE
1: Modbus, Do × 1, Di × 1
2: 4 – 20 mA DC × 4
• All measured values, counter values, display mode,
setting data are stored in the non-volatile memory at the
power off
3: 1 – 5 V DC × 4
• Conversion factors, system configuration, interval times
are programmable using the front buttons
• Open collector output for alarm or energy count
4: 4 – 20 mA DC × 2, Do × 1, Di × 1
5: 1 – 5 V DC × 2, Do × 1, Di × 1
6: 4 – 20 mA DC × 2, Do × 2
7: 1 – 5 V DC × 2, Do × 2
8: Modbus, Do × 3
Typical Applications
• Multi-functional power monitor incorporated in an electric
device: saves space, wiring works, and cost
