ABB AI835A S800 Analog Input Module 3BSE051306R1 8 channels I/O
Module
AI835 3BSE008520R1
AI835A 3BSE051306R1
Description of AI835/AI835A :
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.
