The 1769-OB32 belong to the 1769 Compact I/O. This solid-state device is a discrete output sourcing module that is manufactured by Allen-Bradley for use with CompactLogix Controllers as well as MicroLogix 1500 controllers.

The 1769-OB32 is a high-density module that is equipped with Thirty-Two (32) output channels, isolated in Two (2) groups of Sixteen (16) channels. This module is practical for use in applications where a large number of I/Os are existing, with limited panel space. This module occupies 1.5 slot of the CompactLogix or MicroLogix 1500 chassis to allow maximizing supported module of a specific controller.

The output channel of this module operates at a sourcing input configuration. Individual ON Output delay of each channel measures 0.1 ms and an OFF output delay of 1.0 ms. Each channel may carry a Current of 0.5 A @ 60 °C (140 °F) and 1.0 A @ 30 °C (86 °F).
The 1769-OB32 occupies a 32-Bit register. By accessing the module register, monitoring or I/O forcing may be enabled to support commissioning of the component.

When wring this module, use wire sizes of 22 - 14 AWG for solid wire and 22 - 16 AWG for stranded wire. Install this module beside any adjacent Compact I/O module. Ensure that connection to the backplane by ensuring that the mounting tabs are properly aligned.

The Allen-Bradley 1769-OB32 is Compact I/O module which is a solid-state 24VDC output module. This output module has Thirty-Two (32) channels with Two (2) groups of Sixteen (16) channels each. This module is wired in sourcing configuration to provide. The 1769-OB32 has a 20.4 to 26.4 Volts DC operational voltage range, and an output delay time of 0.5 milliseconds (on-mode) or 4 milliseconds (off-mode). It has a 3000 mA current draw at 5.1 Volts and a maximum heat dissipation of 4.5 Watts. The 1769-OB32 module has a maximum off-state leakage current of 1.0 mA at 26.4 Volts and a minimum on-state current of 1.0 mA.
The Allen-Bradley 1769-OB32 output module also has a maximum on-state voltage drop of 1.0 VDC at 1 Amp and a maximum current per point of 0.5 Amps at 60 degrees Celsius (140 degrees Fahrenheit), and 1.0 Amps current at 30 degrees Celsius (86 degrees Fahrenheit). The 1769-OB32 has a 2.0 Amps surge current for 10 milliseconds, which repeats every 2 seconds. It is a single slot width module that is normally mounted on a mounting plate or a DIN rail. The module has an approximate weight of 450 grams (0.992 pounds) and measures 118 x 52.5 x 87 millimeters (4.65 x 2.07 x 3.43 inches). It has unique IEC Class 2 reinforced insulation and a 6-module power supply distance. The 1769-OB32 module has a terminal torque screw of 0.68 N-m, a copper wire with 22 by 14 AWG solid wire size, or a 22 by 16 AWG stranded wire size.
