The AI893 Analog Input Module has 8 channels. The module includes
Intrinsic Safety protection components on each channel for
connection to process equipment in hazardous areas without the need
for additional external devices.
The module can be configured for either 2 or 3-wire RTD sensors or
for TC sensors. In TC mode, channel 8 be used for Cold Junction
(ambient) temperature measurements, thus serving as CJ-channel for
channel 1...7. The junction temperature may be measured locally on
the MTUs screw terminals, or on a connection unit distant from the
device. The cold junction temperature is measured with a 3-wire Pt
100 sensor. Alternatively, a fix junction temperature for the
module may be set by the user (as parameter). Channel 8 may be used
in the same manner as channel 1-7 when no CJ-temperature
measurement is needed.
TU890 and TU891 Compact MTU can be used with this module and it
enables three wire connection to the process devices without
additional terminals. TU890 for Ex applications and TU891 for non
Ex applications.
Features and benefits
• 8 differential input channels for 2 or 3-wire RTD and
Thermocouple.
• 1 group of 8 channels isolated from ground.
• 15 Bit + sign resolution.
• Ex certified inputs.
