ABB S800 Modules Analog input 8 channels Module AI835A 3BSE051306R1
Description of Input Module 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.
Features and benefits
a:8 channels for RTD (Pt100, Cu10, Ni100 and Ni120 and resistor) inputa;8 differential input channels for thermocouple/mV.
b:Channel 8 can be designated as the CJ-channel (4-wire Pt100 RTD)
c:Variety of thermocouples with the following characteristics: B, C, E, J, K, N, R, S and T for AI835A also D, L and U
d:15 Bit resolution (A/D)
e:Inputs are monitored for wire-break open-circuit
