DESCRIPTION
The 6017 has thirty-two input channels organized in four eightchannel
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 digitalto-
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 programmable 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.
Differential input, ±2 millivolts to ±10 Volts
