Compact™ 1769-OF2 (Series B or Later) Analog Output Module 19

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.

±0.05%

Output Error Over Full Temperature

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)
