ABB AI835｜Analog Input Module｜

AI835

Specification
Channel configuration
8 differential inputs; The 8th channel can be configured as a cold end CJ compensation channel, providing ambient temperature compensation for channels 1-7 and eliminating thermocouple cold end errors
Measurement signal type
Linear millivolt: -30mV~+75mV
Thermocouple TC (AI835 basic model): B, C, E, J, K, N, R, S, T
AI835A adds: D, L, U-shaped thermocouples
Collection performance
AD resolution: 15 bits
Whole machine accuracy: ≤± 0.1% FS
Input impedance:>1M Ω, weak mV signal, high impedance, anti attenuation
Comes with periodic automatic calibration to suppress temperature drift (typical 5ppm/℃)
Wire breakage diagnosis: thermocouple circuit breakage automatic recognition and uploading alarm
Isolation design
The 8-channel group of the entire board is isolated from the ground, with an isolation withstand voltage of 500V AC; There is no independent isolation between channels ABB
