Description

AI835

ABB Ability™ System 800xA® hardware selector

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.

· Channel 8 can be designated as the CJ-channel (4-wire Pt100 RTD).

· Variety of thermocouples with the following characteristics: B, C, E,J, K, N, R, S and Tfor AI835A also D, L and U.

· 15 Bitresolution (A/D).

· Inputs are monitored for wire-break open-circuit.
