The GE-Emerson IC670ALG630 Field Control Thermocouple Input Module converts the input level from its eight independent inputs to a digital value. The module supports a variety of thermocouple types.

Each input can be configured to report data as millivolt or temperature (tenths of degrees Celsius or Fahrenheit) measurements.

When thermocouples are measured, the module can be configured to monitor the thermocouple junction temperature and correct the input value for cold junction.

On command from the module’s internal microprocessor, the solid-state, optically-coupled multiplexer circuitry provides the present analog value of a specified input to the analog-to-digital converter. The converter turns the analog voltage into a binary (15 bits plus a sign bit) value representing tenths (1/10) of degrees Celsius or Fahrenheit. The result is read by the module’s microprocessor. The microprocessor determines if the input is over or under its configured range, or if an open thermocouple condition exists.

When the module is configured to measure millivolts instead of inputs from thermocouples, the result of the analog-to-digital conversion is a value reported in hundredths (1/100) of millivolts.

A Bus Interface Module handles the exchange of all I/O data for the modules in the I/O Station over the communications bus.
