Brand New ABB DO840 3BSE020838R1 Module In Stock

Description

Thermocouple input channels are adjusted for cold junction temperature. The cold junction reference can either be the built-in reference available on the I/O module's termination unit or a value originating from any other function code block output anywhere in the system. The cold junction reference supplied by the controller is assumed to be in degrees C. The ASI module converts this value to millivolts and adds it to the value from the analog-to-digital converter. Thermocouple channels identified to be cold junction reference inputs (FC 216, specification S4) use the built-in cold junction reference on the termination unit for their cold junction compensation.The ASI module maintains a set of adjustment values for each input channel. These values correct for offset and gain errors in the input channel. The raw analog-to-digital converter count value is converted to an actual input signal value using the calibration data. For thermocouple inputs, an adjustment is made for the cold junction temperature of the thermocouple. An additional, user-specified adjustment is then applied, if one has been defined with FC 217. The final corrected input reading is then converted to engineering units using either thermocouple or RTD conversion tables, or the engineering unit zero and span values specified for the input. The following sections describe the various types of input value adjustments.Each input channel is calibrated at the factory. During the calibration procedure, any offset and gain errors are identified and required correction factors are calculated and stored in the analog input module's nonvolatile memory. These factors are used when the input channel is scanned to correct the reading. A calibration adjustment is applied to active channels and the cold junction reference input.
