Fexible I/O module

The E-moduleR technique was adopted for its flexibility and easy expansion of the I/O function of Acuvim IIR. A maximum of 3 modules can be used for one meter. Digital input, Digital output, pulse output, relay output, analog input and analog output are provided by I/O option module.

AlarmsThe limits of the less than 9 indicated parameters can be set with a specified, time interval. If any input of the 9 indicated parameters is over or under its setting limit with persisting time over specified time interval, the event will be recorded with time stamps and trigger the Alarm DO output. The 9 indicated parameters can be any of the following 34 ones.F, V1, V2, V3, Vlnavg, V12, V23, V31, Vllavg, I1, I2, I3, Iavg, In, P1, P2, P3, Psum, Q1, Q2, Q3, Qsum, S1, S2, S3, Ssum, PF1, PF2, PF3, PF, U_unbl, I_unbl, Dmd_P, Dmd_Q, Dmd_S

Data_logging

The Acuvim IIR, model offers 4MB of onboard data logging memory to be used for historical trending. There are 3 assignable historical logs where the majority of the metering parameters can be recorded. A real time clock allows for any logged events to be accurately time stamped.

Time of useUser can assign up to 4 different tariffs (sharp, peak, valley and normal) to different time periods within a day according to the billing requirements. The meter will calculate and accumulate energy to different tariffs according to the meter’s internal clock timing and TOU settings.
