Rockwell Automation 1769-IF4XOF2 Compact 8-Bit Low Resolution Analog I/O Combination Module - Manual (Page 71)

Publication 1769-UM008A-EN-P - November 2001
Specifications A-3
Output Specifications
Calibration Not required. Accuracy is guaranteed by components.
Non-linearity (in percent
full scale) ±0.4%
Repeatability
(5) ±0.4%
Input Channel
Configuration via wiring of devices, 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.
Channel Diagnostics Over range by bit reporting
Maximum Overload at
Input Terminals

Voltage Terminal: 20V continuous, 0.1 mA
Current Terminal: 32 mA continuous, 5V dc
Input Group to Bus
Isolation 500V ac or 710V dc for 1 minute (qualification test)
30V ac/30V dc working voltage
(IEC Class 2 reinforced
insulation)
(1) The over-range flag will come on when the normal operating range is exceeded. The module will continue to
convert the analog input up to the maximum full scale range. The flag automatically resets when within the
normal operating range.
(2) 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, 10V dc input sig nal and 20V dc
potential above ground).
(3) For proper operation, both the plus and minus input terminals must be within 0 to +10V dc of analog common.
(4) Includes offset, gain, non-linearity and repeatability error terms.
(5) Repeatability is the ability of the input module to register the same reading in successive measurements for the
same input signal.
(6) Damage to the input circuit may occur if this value is exceeded.
