Instruction Content
WBPEEUI240766B0 1 - 3
4 to 20 milliampere current.
•
Resolution of the analog-to-digital conversion process is 24
bits.
•
Input type and channel resolution can be selected inde-
pendently for each channel, permitting any mix of inputs
on a single IMASI13 module.
•
Channel isolation and open input detection are provided
for each channel.
•
Input circuit offset, gain, and nonlinearity errors are
recorded during a one time factory calibration procedure.
These measurements provide error compensation during
normal operation. The analog input module does auto-
matic recalibration during normal operation to compensate
for component aging and temperature drift. No user cali-
bration is ever required.
•
Engineering units conversion to degrees C or F is automat-
ically calculated on all input signals that are thermocouple
or RTD types. These conversions correct for nonlinearities
in the conversion to temperature units using industry
standard linearization tables.
•
The analog input module scales the block output value to
engineering units for low and high level voltage inputs.
Input type and zero and span values are specified in
FC 216.
•
Thermocouple inputs have cold junction compensation.
Each termination device has a built-in cold junction refer-
ence. The cold junction reference applied to thermocouple
inputs can be this built-in reference or it can be a remote
reference read from another input from this or another I/O
module.
•
The IMASI13 module can be removed or installed without
turning off power to the system.
