  • Programmable excitation with remote sensing
  • Shunt & voltage calibration
  • Automatic zero & balance
  • Gains 1 to 5,000 with 0.05% accuracy
  • Fixed or programmable filter

  • Two alarms with programmable upper & lower limits

Description

The 6032 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 four-pole low pass 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 a continuous analog output.

The 6032 is used with quarter, half and full bridge transducers, potentiometers and low-level voltage signals in demanding applications such as load control. The EM option adds continuous excitation monitoring with out-of-limit alarms. The PF option adds a four-pole, 4 to 5,000 Hz programmable filter with 1 Hz resolution.

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.
