Measure: three phase I,U,F,P,E,
Output: RS485, Analog, relay output
Output: RS485, Analog, relay output
1. General
PZ Series programmable intelligent three phase current,voltage meter,adopting AC sampling technology,can directly measure current and voltage of three phase grid.It can be used for local display,and connecting industrial control device to form measuring control system.
Meters have RS-485 communication interface,adopt compatible Modbus-RTU protocol can change electric parameter signal into standard analog output or with 1 channel relay alarm output,or with 4 channel(2 channel)switching input/2channel switching output.Based on different request,by pressing related key on instrument panel,parameter setting and control of transformation ratio,alarm,communication etc.can be done..
