SAI-918 Integrated Monitoring Equipment

I. Overview
SAI-918 Digital Integrated monitoring and control devices primarily related to monitoring for generator sets, transformer load tap control , monitoring and control requirements of the power plant substation design and development of the public can also be used for a line or transformer circuit monitoring .
Function Deployment
AC measurement
A set of three-phase current , phase voltage and zero-sequence voltage , electro , frequency , power ﹑ power factor ;
A set of three-phase voltage 380V circuit and one independent zero-sequence voltage measurement ( specify when ordering ) , can be used to measure the transformer substation with ;
Three straight road traffic unit , can be directly measured 4 ~ 20mA, 0 ~ 5V, 0 ~ 220V DC current or voltage , different types of input can be through the exchange board internal jumpers to select , factory set to the first road 4 ~ 20mA, second Road 0 ~ 5V, the third road 0 ~ 220V, when For measuring excitation current , should external 0 ~ 75mV / 0 ~ 5V transmitter module .
Switch input
Can capture 11 -way switch , switch 220V/110V input is optically isolated inputs.
Switch output
There are 10 empty road contact output can jump on 5 ﹑ closing control switch .
