When measuring temperature greater than
or equal to 0 °C and when input terminal
temperature is balanced

500 ms or more 16.7 ms/20 ms
1 s or more 36.7 ms
2 s or more 100 ms
Electromagnetic relay scanner type

2 ch. mode*2
Sampling interval Integration time
100 ms or more 16.7 ms/20 ms
1 s or more 36.7 ms
2 s or more 100 ms
*1 In 10ch mode, when the scan interval is set to 100
ms or 200 ms, the A/D integration time is fixed at
1.67 ms. This prevents power frequency noise
from being eliminated, causing measured values
to wobble.
*2 Cannot be specified for the electromagnetic relay
scanner type (Type Suffix Code: -T1).
• Calibration correction:
Mode: Linearizer Approximation, Linearizer Bias
Number of set points: 12
• Terminal type*: M3 screw terminal or Clamp terminal
* M3 screw terminals only for the electromagnetic
relay scanner type.
• Withstand voltage
Between the input circuits and the internal circuit:
3000 V AC for one minute
Between the analog input channels: 1000 V AC
for one minute (excluding b-terminal)
• Insulation resistance:
Between the input terminal and the internal
circuit: 20 MΩ or greater at 500 VDC
• Recommended replacement period of
electromagnetic relay scanner type modules:
Electromagnetic relay scanner type modules
make measurements by switching mechanical
contact relays on and off.
To ensure that the modules continue to operate
reliably and correctly, replace them
Continuous use at measurement interval 1 s: 1 year
Continuous use at measurement interval 2 s: 2 years
Continuous use at measurement interval 5 s: 5 years
