• Common-mode interference (U
CM
< 60 V AC)
• Series mode interference (peak value of disturbance <
rated input range)
> 100 dB
> 90 dB **
Crosstalk between inputs > 100 dB
Operational limit (across temperature range, relative to 0 °C to 60 °C input range). Note: This limit does not cover the cold
junction error
