Device type

• Top-hat rail mounted device
• Plastic case 96 mm ? 96 mm ? 100 mm / 3.78 in. x 3.78 in. x 3.94 in. (W ? H ? D)
• Degree of protection: IP20

Input and output circuits

• 4 inputs for alternating voltage measurements
• 3 inputs for alternating current measurements up to 10 A continuous
• 4 optional DC analog outputs freely configurable:
  • Direct currents: 0 mA to 20 mA, 4 mA to 20 mA and -20 mA to 20 mA
  • Direct voltages: 0 V to 10 V and -10 V to 10 V
• Individually programmable binary outputs

Signalization LEDs

Automatically monitor the functions of its hardware, software, and firmware components.

Communication

• Ethernet: IEC 61850 or MODBUS TCP communication protocol
• Optional serial RS485 interface that enables the device to communicate via the MODBUS RTU or the IEC 60870-5-103 communication protocol.

Measurands

The following measurands can be recorded or calculated from the measured quantities:

• TRMS (True RMS) for alternating voltage and current
• Active, reactive and apparent power
• Active, reactive and apparent energy
• Power frequency
• Phase angle
• Power factor and active power factor
• Voltage and current unbalance
  • Mean value of the 3 phase voltages: Vavg
  • Mean value of the 3 phase currents: Iavg..

Time synchronization

• For a common time basis when communicating with peripheral devices and time stamping of the process data.
• External time synchronization via Ethernet NTP
• External time synchronization via field bus using the MODBUS RTU or the IEC 60870-5-103 communication protocol
• Internal time synchronization via RTC (if external time synchronization is not available).

Response time for analog and binary outputs

The faster response time of the analog and binary output is a very important feature of SICAM T that enables a reliable reaction of the controlling applications. The response time of the device is 120 ms at 50 Hz and 100 ms at 60 Hz.
