The Allen-Bradley 1769-OF2 is a Two (2) channel analog output module. This module is a single-slot width module with each channel capable of providing analog voltage and current signals such as ± 10VDC, 0 to 10VDC, 0 to 5VDC, 1 to 5VDC and 0-20 mA and 4-20 mA. This output module may be used to drive modulating devices, re-transmit analog data to another receiving element such as panel meters and data logger and as input of signal isolators and splitters.

The 1769-OF2 features Two (2) single ended output channels with sigma-delta Digital-to-Analog (DAC) converter. Depending on the configured output signal, the module’s resolution are ±10V dc: Sign + 14 bits, 0.64 mV 0 to +5V dc: Sign + 13 bits, 0.64 mV 0 to +10V dc: Sign + 14 bits, 0.64 mV +4 to +20 mA: Sign + 14 bits, 1.28 µA +1 to +5V dc: Sign + 13 bits, 0.64 mV 0 to +20 mA: Sign + 14 bits, 1.28 µA. Overall, the digital resolution across full range is 14 bits (unipolar); 14 bits plus sign (bipolar) with conversion rate 2.5 ms and step response of 2.9 ms.

The 1769-OF2 output may be linked to Proprotional + Integral + Derivative (PID) controller, used for implementing manual and automatic control of analog control loops. If used with MicroLogix 1500, the appropriate configuration of this module is RSLogix 500. If used with CompactLogix version 20.11 or lower, compatible software is RSLogix 5000 programming software while Studio 5000 Logix designer is used if the CompactLogix controller has version 21.00 and higher.

The 1769-OF2 has a current load of 10 mA and a restive load on-current output of 0 to 500 ? (inclusive of wire resistance). It has a load-on voltage output range greater 1 k ? at 10 Volts DC and an inductive load per current output of 0.1 mH. The 1769-OF2 has a capacitive load per output voltage of 1 µF. It requires no field calibration and an accuracy margin of ±0.5% (Voltage full range at 25 degrees Celsius or 77 degrees Fahrenheit), and a ±0.35% (Current full range at 25 degrees Celsius (77 degrees Fahrenheit)). The 1769-OF2 compact voltage/current output module has a module error boundary around 0.8%, and an accuracy drift of ±0.0086% per degree Celsius. The output module also has a repeatability and nonlinearity margin of ±0.05%, and an output impedance of 15 ? .

The 1769-OF2 has a ±0.05% offset error margin and a 10ms time to detect an open wire condition. It equipped with short-circuit (21 mA maximum) and over-voltage protection. It has a copper wire with a 22 by 14 AWG solid size and single slot width. The 1769-OF2 has a weight of 0.65 pounds and dimensions of 4.65 by 1.38 by 3.43 inches.
