Description
The 6017 has thirty-two input channels organized in four eight-channel groups. The eight inputs in each group are multiplexed to a programmable gain differential amplifier and digitized with 16-bit resolution then output to the Series 6000 data bus. Each channel is capable of digitizing at up to 2,000 samples per second. The differential inputs have 50 Megohm input impedance and are protected to ±25 Volts.
The 6017 is used to digitize low and high-level signals such as thermocouples or the output of signal conditioning amplifiers. The architecture, which limits the multiplexer to eight channels per amplifier, provides low channel-to-channel crosstalk and high accuracy.
A voltage calibration input is provided in each group of channels for gain calibration of the differential amplifier and analog to digital converter. Both gain and zero calibration employ digital-to-analog converters with the calibration DAC settings stored in non-volatile memory on the module. Zero calibration is automatic and gain calibration is automatic when using PI660 software and a traceable calibration reference.
Upper and lower programmable alarm limits are provided and checked each time the output is digitized. In conjunction with a digital I/O module, the alarms may be used to control external equipment.
