Allowable wiring resistance:
100 Ω or less
Effect of wiring resistance:
NDIS 50 ppm of rdg. / Ω (when using remote sensing wire)
Does not compensate for clamp wiring resistance. Depends on
the gauge resistance.
Allowable input voltage:
±10 VDC (between H-L) continuous
Allowable common-mode voltage: Channel-to-channel: 30 VACrms
Between input and ground: 250 VACrms (-B12, -B35), 30 VACrms
(-NDI)
However, NDIS connector shell is connected to earth potential.
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
(voltage conversion value at 50/60 Hz ±0.1%, bridge voltage of 2 V)
Normal mode rejection ratio:
For integral time of 16.67 ms or more: 40 dB or more (50/60 Hz ±
0.1%)
For integral time of 1.67: 50/60 Hz is not rejected.
(voltage conversion value given a bridge voltage of 2 V)
Insulation resistance
*
: Between input and earth
20 MΩ or more (500 VDC)
Withstand voltage
*
: Between input and earth
2300 VAC for one minute
Channel-to-channel: 30 VACrms or less
Power consumption: Approx. 3 W (one module)
Weight:
Approx. 0.5kg.
External dimensions: Approx. 57 (W) × 131 (H) × 151 (D) mm (including the terminal
cover)
Terminal type:
-B12, -B35: Clamp, terminal board is detachable
-NDI: NDIS, detachable by channel
Applicable wire size: 0.14 to 1.5 mm

(AWG26 to 16) (excluding -NDI)
* Does not apply to the NDIS terminal.
Effects of Operating Conditions
The specifications below apply when the integration time is 16.67 ms or more.
Warm-up time:
At least 30 minutes after power-up
Effects of ambient temperature:
The effect received by changes in 10°C increments of the ambient
temperature is
±(0.1% of range) or less
Effects of power fluctuation:
Meets the accuracy specifications for AC power supply in the
range 90 to 132 V and 180 to 250 V
Effects of magnetic field:
The fluctuation in external magnetic fields for AC (50/60 Hz) 400
A/m is ±2% of range or less
Effect of position:
Horizontal with the feet at the bottom is the rule.
