3.4.3 Module / Ch.
(1) Meaning
This item is for setting of Module ID and number of Input Channel for I/O module or Input
module to be used.
3.4.4 Quantities
(1) Meaning
This item is for setting of the physical quantity as the measurement objective of the sensor to
be used.
3.4.5 Input Type
(1) Meaning
This item is for setting of the type of a sensor signal to be used as an electric signal when it is
inputted to K2 system.
Three types of input format as below are supported for I/O Board or Input Board ;
1. AC Voltage Input : ±10 V FS
2. DC Voltage Input : ±10 V FS
3. Charge Input : ±10000 pC FS (charge amplifier gain 1mV/pC)
4. Charge Input : ±1000 pC FS (charge amplifier gain 10mV/pC)
5. IEPE Input : ±10 V FS
‘Charge Input’ is selected when the acceleration pickup output of charge output type is
directly connected to the I/O Module or Input Module.
I/O Module and Input Module are available to select both of gains because these modules have
a charge amplifier for converting Charge/Voltage internally.
Please select a suitable gain according to the maximum acceleration level generated in the test
to be operated.
To connect the IEPE output type acceleration pickup output directly to the I/O module or input
module, select ‘IEPE input’.
A CCLD amp (+ 24 VDC, 3.5 mA) is built in the I/O module or input module.
When other sensors are to be used, the voltage signal obtained by operating all the proper
voltage conversion should be inputted. This item is to be set to ‘Voltage Input’.
3.4.6 Sensitivity
(1) Meaning
This item is for setting of input sensitivity of the signal inputted to the input channel to be
used.
