AI 835 AI835 ABB 800XA CONTROL SYSTEM 3BSE008520R1 ANALOG INPUT 8 CH

AI835 3BSE008520R1 Analog Input 8 ch ABB Advant 800xA

Product Details:

The AI835/AI835A provides 8 differential input channels for Thermocouple/mV measurements.

Measurement ranges configurable per channel are: -30 mV to +75 mV linear, or TC Types B, C, E, J, K, N, R, S and T, for AI835A also D, L and U.

One of the channels (Channel 8) may be configured for “Cold Junction” (ambient) temperature measurements, thus serving as CJ-channel for

Ch. 1...7. The junction temperature may be measured locally on the MTUs screw terminals, or on a connection unit distant form the device.

Alternatively, a fix junction temperature for the module may be set by the user (as parameter) or for AI835A also from the application. Channel 8

may be used in the same manner as Ch. 1...7 when no CJ-temperature measurement is needed.

Features and benefits

• 8 differential input channels for thermocouple/mV.
