Fexible I/O module

The E-moduleR technique was adopted for its flexibility and easy expansion of the I/O function of Acuvim IIE. 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.

Alarms
The 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
