R-8074

Multifunctional Intelligent Electricity Transmitting Module

Main Features

-  Measured Channels: Three-phase voltage and current, and expansion I/O function

-  Measured Parameter: the real effective value of current and voltage, power factor, active power, reactive power, frequency, power factor, input active electrical degree, output active electrical degree, main electrical degree, reactive electrical degree, apparent power, main apparent power.

-  Input Frequency:45~75Hz

-  Voltage Range: 10~500V, can measure higher voltage by appending voltage transformer and setting voltage transformation ratio.

-  Current Range: Basic range is 0~5A, can measure greater current by

   appending current transformer, and setting current transformation ratio.

-  Signal Processing:16bits A/D converter,6 channels, every channel synchronistical AC samples at the speed of 4KHz.The real time data of module is real effective value of 1 second( refresh one time a second)

-  Overload Capability: Can measure exactly 1.4 times of range input;  instant current ( 10 cycles) is 5 times, no damage when voltage range is 3 times.

-  Output Data: Electric parameters such as three-phase voltage Ua, Ub,

   Uc; three-phase current Ia, Ib, Ic; active power P, reactive power Q, power

   factor PF, frequency f, active power of each phase Pa, Pb, Pc; reactive

   power of each phase Qa, Qb, Qc; forward active electrical degree,

   reversed active electrical degree, forward reactive electrical degree,

   reversed reactive electrical degree.

-  Output Interface:RS-485/RS-232
-  Communication Rate:1200,2400,4800,9600BPS

-  Communication protocol: ASCII commands and MODBUS/ASCII protocol

-  Degree of Accuracy: current, voltage: 0.2, the rest: 0.5

-  Parameter Setting: Module’s address, communication rate, setting voltage and current transformation ratio by communication port

-  Power Supply: +10V~+30VDC

-  Built-in instrument transformer is with boundary alarm, short-phase alarm, overload alarm, over-voltage alarm, and under-voltage alarm.

-  Built-in real-time clock provides the information of year, month, day, and hour, minute and second, to make sure supplying electricity uninterruptedly for 10 years with lithium cell.
