Approx. 1 s
Calculates the moving average for the specified number of past process values (1 to
16), and stores that value in the CIO Area as the process value.
Process value 4-point alarm (HH, H, L, LL), hysteresis, and ON-delay timer (0 to 60 s)
are available.
Calculates the amount of change per comparison time interval (1 to 16 s).
Rate-of-change 2-point alarm (H, L), alarm hysteresis (shared with process value
alarm), and ON-delay timer (0 to 60 s, shared with process value alarm) are available.
When the process value scaling maximum value is A and the minimum value is B:
Output =
(A−B) (Input−B)
Dropout: Output approx. 7% maximum linear (output = input) characteristics
Note The square root function is only enabled when the maximum scaling value is
greater than the minimum value.
Note When square root processing is being performed, set the maximum and mini-
mum scaling values to the values required after square root processing of the
current or other input values.
Between analog inputs and between input terminals and PC signals: Isolation by
transformer
20 MΩ (at 500 V DC) between inputs
Between inputs: 1,000 V AC, at 50/60 Hz, for 1 min, leakage current 10 mA max.
Terminal block (detachable)
Set by rotary switches on front panel, from 0 to 95.
Three LED indicators on front panel (for normal operation, errors detected at the Ana-
log Input Unit, and errors related to the CPU Unit).
