Detailed data
ABB AI835 3BSE051306R1 Analog Input Module
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.

Frequently asked questions about the product are as follows:
-What is ABB AI835 3BSE051306R1?
ABB AI835 3BSE051306R1 is an analog input module in ABB Advant 800xA system, mainly used for thermocouple/mV measurement.
-What are the aliases or alternative models of this module?
Aliases include AI835A, and alternative models include U3BSE051306R1, REF3BSE051306R1, REP3BSE051306R1, EXC3BSE051306R1, 3BSE051306R1EBP, etc.
What is the special function of channel 8?
Channel 8 can be configured as a "cold junction" (ambient) temperature measurement channel, as a cold junction compensation channel for channels 1-7, and its junction temperature can be measured locally on the screw terminals of the MTU or on a connection unit away from the device.
