Analog Input Module SAI06
Item Specification
Model name SAI06
Number of input points 8 points
Input insulation unit 8 points are isolated together (input(-) side common)
Input signal level
Bipolar:
10 mVdc,
20 mVdc,
50 mVdc,
100 mVdc,
1 Vdc,
5 Vdc*
Unipolar: 1-5 Vdc*
Each point can be set independently. However, it is not possible to set
bipolar and unipolar together.

Input impedance
1 M
or more
Data update period Bipolar: 355 ms/302 ms (50 Hz/60 Hz filter)*
Unipolar: 40 ms
A/D conversion data Bipolar: -32000 to +32000 counts
Unipolar: +6400 to +32000 counts
CMRR 100 dB or more (100 Vac, 50/60 Hz)
Standard input accuracy
Within
0.1% of full scale
Temperature drift
Within
0.015%/
C
Power supply voltage drift
0.1% of full scale (in a system power supply fluctuation of
10%)
Input wire break characteristics Down scale
Input wire break detection time Bipolar: Within 2 seconds Unipolar: Within 10 seconds
Diagnosis of trouble Analog standard voltage, I/O bus transmission, CPU, memory, analog
input value comparison diagnosis (implemented on SBIF2. The
diagnosis is implemented under dual system.)
Dualization Possible (Two units are mounted on terminal block units
UTBA6/UTBA61 or I/O base unit UABU3.)
Dualized switching condition When a major alarm (such as ADC error or I/O bus transmission
interruption) has occurred to the online module
Address setting Set the address by selecting between 1 and E (1 to 14) by front panel
address setting switch. (For duplexed configuration, set both the primary
and secondary modules to the same address)
Insulation resistance
100 M
or more (measured with 500 Vdc megger, between total inputs
and internal circuits)
Ability of insulation to withstand voltage 500 Vac for 1 minute (between total inputs and internal circuits)
Current consumption 24 Vdc-50 mA or less (I/O system power supply)
Internal heat generation 1.2 W or less (rated condition)
Compatible terminal block units UTBA1 (for single configuration),UTBA3 (single configuration; used
together with SDA01),UTBA6 (for dualized configuration),UTBA61(for
dualized configuration)
