5.2 Main Module Specifications
Measurement
Style number: S2
Measurement range and accuracy:
See the measurement range and accuracy given in the
specifi cations of each input module.
Maximum number of inputs:
60 inputs (however, only up to six modules can be controlled)
Measurement interval: Select from 10, 50, 100, 200, 500 ms, 1, 2, 5, 10, 20, 30, or 60 s.
Up to three intervals defi ned for the input modules can be set
(multi-interval)
Also, the following limitations apply to the measurement interval
and number of measurement channels.
Measurement Interval Number of measurable channels
10 ms 10
10 ms and 50 ms mixed. 10
50 ms 30
Synchronization between modules:
Synchronized within the same sampling interval (in the same unit)
Synchronization between channels:
4-CH, High-Speed Universal Input Module and Digital Input
Module: Synchronized between channels
10-CH, Medium-Speed Universal Input Module, Six-Channel
Medium-Speed Four-Wire RTD Resistance Input Module, and the
4-CH, High-Speed Digital Input Module: Due to the scanner type,
not synchronized between channels
Filter function: First-Order Lag Filter
Applicable measurement types: For each channel of DC voltage,
thermocouple, RTD, strain, and resistance, you can select a
time constant (time until 63.2% of the output value is reached)
corresponding to the sampling interval indicated in the table below.
Time constant = measurement interval × N (where N = 5, 10, 20,
25, 40, 50, or 100)
Measurement Interval (s) Selectable Time Constants (s)

60 300 600 1200 1500 2400 3000 6000
Measurement groups: Measurement channels can be divided into up to 3 groups by
module. The measurement interval must be the same for all
channels in the group.
