Input bias current
max. 10nA
Dielectric strength
Between input terminals : 1000V AC (50/60Hz) for one minute
Between an input terminal and ground : 1500V AC (50/60Hz) for one minute
Input source resistance
DCV, TC : 2k
Ω or lower
RTD : 10 Ω or lower per line (Pt100Ω)
5
Ω or lower per line (Pt50Ω)
1
Ω or lower per line (Cu10Ω)
Temperature coefficient
zero : 0.01% of range/ °C
full span : 0.01% of range/ °C (0.02% of span/°C for Cu10Ω)
Thermocouple burnout
Detected in a thermocouple range (On/Off) enabled, current of 4
µA, detectable pulse width of
approx. 5ms
2 k
Ω or lower is considered “normal”
100 k
Ω or greater is considered “disconnected”
Detection interval for thermocouple burnout
2.5 sec. for a measurement period of 0.5 sec; in all other cases: each measurement interval
Detection timing for thermocouple burnout
The burnout condition is detected at each measurement interval. However, with a 10ch universal
input module connected and a measurement interval of 0.5sec, the minimum interval of the
burnout detection becomes 2.5 sec.
Power consumption
Included in the main unit or the subunit to which the module is to be installed.
