Publication 1769-IN049A-EN-P
Specification 1769-OF2 (Series B or later)
Accuracy Drift with Temperature Voltage Terminal: ±0.0086% FS per °C
Current Terminal: ±0.0058% FS per °C
Output Ripple
(1)
range 0 to 50 kHz
(referred to output range)
(1) Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
±0.05%
Non-linearity (in percent full scale) ±0.05%
Repeatability
(2)
(in percent full scale)
(2) Repeatability is the ability of the output module to reproduce output readings when the same controller
value is applied to it consecutively, under the same conditions and in the same direction.

Rated Working Voltage
(3)
(3) 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 signal
and 20V dc potential above ground).
30V ac/30V dc
Output 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)
Module OK LED 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 by bit reporting
output wire broken or load resistance high by bit reporting
(current mode only)
