*1 Because the power supply frequency noise is not rejected, the measured vales may fluctuate especially with
temperature measurement using thermocouples. In such cases, increase the measurement interval, or use
the 4-CH High-Speed Universal Input Module or the 10-CH, Medium Speed Universal Input Module.
*2 For DC power, set to 20 ms.
*3 When synchronizing time by SNTP, the integral time is the same as when the measurement interval is 1 s.
*4 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.
Reference junction compensation:
Switch external/internal by channel, includes remote RJC function
Reference junction compensation accuracy:
When measuring temperature greater than or equal to 0 °C and
when the temperature of the input terminal is balanced
Type R, S, W: ±1°C
Type K, J, E, T, N, L, U, XK GOST: ±0.5°C
Type N (AWG14), PLATINEL, NiNiMo, WRe3-25, W/WRe26: ±1°C
Note: Type B and PR40-20 internal RJC is fixed at 0°C
Maximum input voltage: DC voltage at 1-V range or less, TC, and DI (contact): ±10 VDC
(continuous)
Other measurement ranges: ±120 VDC (continuous)
Normal-mode voltage: DC voltage, TC, DI (LEVEL): 1.2 times the range rating or less
(50/60 Hz, peak value including the signal component)
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:
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
(50/60 Hz ±0.1%, 500 Ω unbalanced between minus
measurement terminal and ground)
Common-mode voltage between channels: 120 VACrms (50/60 Hz)
Noise rejection:
Rejection by the integrating A/D converter and the use of low pass
filters
Input resistance: For DC voltage 1 V range or less and thermocouple range: 10 MΩ
or less
For DC voltage 2 V range or higher: Approx. 1 MΩ
Insulation resistance: Between input and ground: 20 MΩ or more (500 VDC)
Input bias current:
10 nA or less (except for burnout setting)
Withstand Voltage: 1000 VAC (50/60 Hz) for one minute between input terminals
3700 VAC (50/60 Hz) for one minute between the input terminal
and earth terminal
Input signal source resistance:
DC voltage, thermocouple: 2 kΩ or less
Thermocouple burnout: Detection at a specifi ed detection interval per measurement
interval and detection within the thermocouple range (detection
ON/OFF possible)
