DESCRIPTION

The 6013 input module has eight channels, each with programmable gain instrumentation amplifier, low pass filter and sample and hold. The high level outputs are multiplexed and digitized to 16 bits then output to the 6000 data bus. A ninth reference temperature channel conditions the output of the temperature sensor in the Model 6084 thermocouple reference junction box The 6013 provides regulated DC power for transducers with integral electronics. Each channel has a wideband analog output.

The 6013 may be configured for use with voltage, thermocouple and current transducers. It provides ±12/15 Volt power for transducers with integral electronics. Versions are available for current loop, high voltage and 28 Volt powered transducers.

Voltage substitution is provided for channel gain calibration utilizing an external voltage standard. A calibration attenuator enables the voltage standard to be used on its highest accuracy ranges and provides a post-attenuator output for calibration and verification. Using Pacific's PI660 software zero and gain calibration and correction are automatic.

The four-pole, low-pass filter uses an easily changed plug-in module to set bandwidth. Either the wideband or filtered output may be digitized and sent to the 6000 data bus. Two programmable alarms each with upper and lower limits are checked each time the outputs are digitized.
