Multi-Function Meter

MODEL: R-27 SERIES

R-27 series multifunction network instruments can measure more than 50 electrical parameters in the electrical circuit.
It has 2-channel electrical energy pulse outputs, 4-channel switching value inputs and RS 485 communication output with modbus protocol. 4 channel switching value outputs or 4 channel transmitting outputs are also available.
