IC200ALG630
ANALOG INPUT 16BIT
THERMOCOUPLE 7CH
OK
The module receives power from the backplane power supply. No external
power source is required.
Each input channel can be configured to report millivolts ranges as 1/100 of
millivolts, or thermocouple inputs as linearized temperature in tenths of °Celsius
or Fahrenheit, with or without cold junction compensation.
LED Indicators
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 thermocouple, non-volatile memory
storage, high/low alarm and thermistor error 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.
