The 6053 input module has four channels of high performance signal-conditioning amplifier-digitizers for strain gages and bridge transducers. Each channel has programmable excitation with remote sensing, voltage calibration, local or remote shunt calibration, programmable gain instrumentation amplifier and six-pole low pass programmable filter. 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 provides two continuous, calibrated analog outputs.
The input and excitation are isolated from the outputs, power, and control interface. This gives the user complete freedom to ground the input without creating ground loops that introduce noise and offset errors.
The 6053 is used with quarter, half and full bridge transducers, potentiometers and low-level voltage signals in demanding applications such as load control. The filter is a six-pole programmable filter with cutoff frequency from 10 Hz to 20 kHz.
Voltage substitution using an external voltage standard is provided for traceable gain calibration. Internal or external shunt calibration is provided for transducer calibration. Transducer balance, zero, and gain calibration are automatic. Two programmable alarms with upper and lower limits are checked for each digitized output. The high-level analog outputs provide a means to independently monitor or record each channel.
