DescriptionThe 6B Series of modules and boards provides the hardware needed to implement a flexible, distributed monitoring and control application. By selecting only the modules and interfaces needed and
The 6B11 and 6B11HV are single-channel isolated signalconditioning modules which accept the outputs from thermocouple, milli-volt, voltage, and process current signals. Unlike conventional signal conditioners, the 6B11 and 6B11HV are complete microcomputer-based data acquisition systems. A major advantage of the onboard microcontroller is its ability to
be remotely reconfigured for various sensor types and input
ranges.
Synchronized Sampling The synchronized sampling command allows data to be sampled simultaneously from all 6B11, 6B11HV, 6B12, 6B12HV modules and all 6B50 boards in a
6B Series system. Each module or board stores the data in a separate register within its microcontroller and can access the data with a separate command.
Software Configuration The 6B11 and 6B11HV linearize and compensate J, K, T, E, R, S and B thermocouples. Additionally, these modules also digitize milli-volt and voltage ranges from+15mV to +5V as well as 0 to +20mA process current inputs. Software is used to configure the 6B11 and 6B11HV modules for address, input range, baud rae, data format, checksum status and integration time. All programmable parameters are stored in the nonvolatile memory of the module.
Each analog input signal is conditioned and scaled by a programmable-gain amplifier and digitized by a 16-bit integrating converter under microprocessor control. The digitized value is passed serially across a magnetically isolated barrier (1500 V rms Model 6B11, 2500 V rms Model 6B11HV) and clocked in by a custom controller chip. The onboard microprocessor then converts the data into engineering units as determined by the channel parameters. In between conversions, the microprocessor auto zeros the offset and gain by monitoring the on-board temperature and compensating for reference drift. Cold junction compensation (CJC) is also performed at this stage. The 6B11 and 6B11HV use
compensation factors to ensure the highest accuracy possible.
