*1 When the measurement interval is 100 ms or 200 ms, measured values may fluctuate (especially for temperature,
20 Ω, and other measurements) since power supply frequency noise is not rejected. In such cases, set the
measurement interval to 500 ms or more.
*2 For DC power, set to 20 ms.
*3 When synchronizing time by SNTP, the integral time is set to 36.67 ms. Also in this case, noise of 50 Hz, 60 Hz, and
their integer multiples is rejected.
*4 When synchronizing time by SNTP, the integral time is set to 100 ms. Also in this case, noise of 10 Hz and its integer
multiples is rejected.
Maximum input voltage:
DC voltage at 1-V range or less, RTD, resistance, and DI (contact):
±10 VDC (continuous)
Other measurement ranges: ±120 VDC (continuous)
Normal-mode voltage:
DC voltage, DI (LEVEL): 1.2 times the range rating or less (50/60
Hz, peak value including the signal component)
Resistance 2 kΩ, RTD 100 Ω, 500 Ω: 1000 Ω types: 50 mVpeak
Resistance 200 Ω, RTD 10 Ω, 25 Ω: 50 Ω types: 10 mVpeak
Resistance 20 Ω: 4 mVpeak
Normal-mode rejection ratio:
For integration time of 16.67 ms or more: 40 dB or more (50/60
Hz ±0.1%)
For integration time of 1.67 ms: 50/60 Hz is not rejected
Common-mode voltage: 600 VACrms (50/60 Hz), reinforced (double) insulation
Common mode rejection ratio (50/60 Hz ±0.1%, 500 Ω unbalanced between minus
measurement terminal and ground. The RTD and resistance
ranges indicate the voltage conversion value when current flows)
When the integration time is 16.67 ms or more: 120 dB or more
When the integration time is 1.67 ms: 80 dB or more
Common-mode voltage between channels:
DC voltage, DI: 120 VACrms (50/60 Hz)
RTD, resistance: 50 VACrms (50/60 Hz)
