Analog Input, 16 Bit RTD, 4 Channels
LED Indicators
The green FLD PWR LED indicates the presence of both backplane power and field
power for the analog field-side circuits. The absence of either backplane or field power
turns off the FLD PWR LED.
The OK LED indicates module status:
On green indicates normal operation
Flashing green indicates boot mode or update
Flashing amber indicates self-diagnostic error
Off indicates no 3.3V backplane power
Diagnostics
The module reports over/under range, open wire, non-volatile memory storage, high/low
alarm, and input short diagnostics to the I/O Fault Table.
Calibration
The module automatically performs A/D calibration at powerup. Automatic calibration is
then repeated periodically to compensate for changes in the ambient temperature.
Host Interface
The RTD Input module provides 4 words of analog input data.
