Publication 1769-IN026C-EN-P - February 2010
Module error over full temperature
range
(0…60 °C (32…140 °F))
See Calibrated Accuracy - 1769-IT6 on page 22.
CJC sensor accuracy ±0.3 °C (±0.54 °F)
CJC accuracy ±1.0 °C (±1.8 °F)
Power supply distance rating 8 (The module cannot be more than 8 modules away from the Compact
I/O power supply. See
page 7 for suggested placement when using AC
power supplies.)
Input group to bus isolation 720V DC for 1 min (qualification)
30V AC/30V DC working voltage (IEC Class 2 reinforced insulation)
Channel-to-channel Common mode
separation, max ±10V DC
Input channel configuration Via configuration software screen or the user program (by writing a
unique bit pattern into the module’s configuration file); refer to your
controller’s user manual to determine if user program configuration is
supported
Module OK status indicator On: module has power, has passed internal diagnostics, and is
communicating over the bus
Off: Any of the above is not true
Channel diagnostics Over- or under-range and open-circuit by bit reporting
Vendor I.D. code 1
Product type code 10
Product code 36
(1) Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input
signal and the value that floats above ground potential (for example, 30V DC input signal and 20V DC potential above
ground).
(2) For proper operation, both the plus and minus input terminals must be within ±10V DC of analog common.
(3) Repeatability is the ability of the input module to register the same reading in successive measurements for the same input
signal.
(4) Open-circuit detection time is equal to channel update time, which is based on filter frequency.
(5) Maximum current input is limited due to input impedance.
