Model 6033 may not be regularly available. Please see Model 6035, 6038 or 6039 for similar applications.
The 6033 input module has eight channels of transducer signal conditioning and digitizer. Each channel has regulated voltage excitation, programmable gain instrumentation amplifier, four-pole low pass filter and sample and hold amplifier. The high level outputs are multiplexed and digitized to 16 bits then output to the 6000 data bus. In addition to the digitized output, each channel has a wideband analog output.
The 6033 is used with 1/4, 1/2 and full bridge transducers, potentiometers and low-level voltage signals. It is particularly suited to strain gages where remote sensing is not a requirement. A shielded four-wire input provides signal and excitation connections to the transducer. Excitation is programmable from 0 to 12 Volts for all channels on the module. An individual regulator for each channel prevents loading or a short on one channel from affecting other channels. A calibration mode is provided that measures excitation voltage or current.
Voltage substitution is provided for gain calibration using an external voltage standard. A calibration attenuator enables the voltage standard to be used on its highest accuracy ranges and has a post-attenuator output for verification and calibration. Resistive shunt is provided for transducer calibration. Two alarm with programmable upper and lower limits are provided and checked each time the output is digitized. Analog outputs provide a means to independently monitor or record each channel.
