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

Range

(0 to 60°C [+32 to +140°F])

Voltage: ±0.8%

Current: ±0.55%

Output Offset Error

(0 to 60°C [+32 to +140°F])

±0.05%

Output Impedance 15 Ω (typical)

Open and Short-Circuit Protection Yes

Maximum Short-Circuit Current 21 mA

Output Overvoltage Protection Yes

Time to Detect Open Wire

Condition (Current Mode)

10 ms typical

13.5 ms maximum

Output Response at System Power

Up and Power Down

± 0.5V dc spike for < 5 ms

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)
