Detailed data
GE IC670ALG630 Thermocouple Input Module
The Thermocouple Analog Input Module (IC670ALG630) accepts 8 independent thermocouple or millivolt inputs.
Module features include:
-Self-calibration
-Two data acquisition rates based on 50 Hz and 60 Hz line frequencies
-Individual channel configuration
-Configurable high alarm and low alarm levels
-Reports open thermocouple and out of range alarms
Each input channel can be configured to report:
-millivolts ranges as 1/100 of millivolts,OR: thermocouples as linearized temperature in tenths of degrees Celsius or Fahrenheit, with or without cold junction compensation.
About Power Sources This module does not require a separate power supply to operate.
The Thermocouple Input Module accepts eight inputs from thermocouples and converts each input level to a digital value. The module supports a variety of thermocouple types, as listed in the Module Specifications section.
Each input can be configured to report data as either millivolts or temperature (tenths of degrees Celsius or Fahrenheit) measurements.
When measuring thermocouples, the module can be configured to monitor the thermocouple junction temperature and correct the cold junction input value.
Upon command from the module's internal microprocessor, a solid-state optically coupled multiplexer circuit provides the current analog value of the specified input to the analog-to-digital converter. The converter converts the analog voltage into a binary (15 bits plus a sign bit) value representing one-tenth (1/10) degrees Celsius or Fahrenheit. The result is read by the module's microprocessor. The microprocessor determines if the input is above or below its configured range, or if an open thermocouple condition exists.
When the module is configured to measure millivolts instead of thermocouple inputs, the result of the analog-to-digital conversion is reported in units of one hundredth (1/100) of a millivolt.
A Bus Interface Module handles the exchange of all I/O data for the modules in the I/O Station over the communications bus.
