1.7 Functions of the 4-CH, Medium-Speed Strain
Input Module (-B12, -B35, and -NDI)
This module is equipped with four inputs and measures strain from strain gauges and
from strain gauge type sensors at a minimum measurement interval of 100 ms.

* Since the power supply frequency noise is not rejected, the measured vales may fluctuate. In such
cases, set the measurement interval to 200 ms or higher.
Measurement Synchronization
The module is equipped with a single A/D converter, and measurement is made
sequentially. Therefore, measurements of each channel are not synchronized.
Common Mode Voltage
For -B12 or -B35
The common mode voltage between channels in a single module when applied
continuously is 30 VACrms, or 250 VACrms between input and ground.
For -NDI
The common mode voltage between channels in a single module when applied
continuously is 30 VACrms, and 30 VACrms between input and ground (shell is non-
isolated).
