PRODUCT INFORMATION
Product Overview
The ABB AI835A 3BSE051306R1 is an S800 I/O Analog Input Module designed for temperature and voltage monitoring. It provides eight differential input channels configurable for millivolt or thermocouple measurements. Supported sensors include thermocouple types B, C, D, E, J, and K. Types L, N, R, S, T, and U are also supported. It also accepts linear inputs ranging from -30 mV to +75 mV.
Channel 8 can be configured for cold junction temperature measurement to serve channels 1 through 7. The junction temperature can be acquired locally on module termination unit terminals or remotely. Alternatively, fixed junction temperatures can be assigned through parameters or the control application. When cold junction compensation is unneeded, channel 8 operates as a standard differential input.
