The 1769‑OB16 from Allen‑Bradley is a high-density output module designed for the CompactLogix and MicroLogix 1500 control platforms. This module provides sixteen solid-state DC outputs, all arranged within a single output group. As a result, it delivers efficient and reliable switching performance for a broad range of industrial DC loads. For instance, you can use it to control solenoid actuators, pilot lights, DC relays, and other 24V DC devices. Consequently, the 1769-OB16 offers a space-saving solution for applications requiring multiple discrete outputs.
Furthermore, this module supports a nominal voltage of 24V DC, with an operating range from 20.4V DC up to 26.4V DC. This wide tolerance ensures stable operation even under slight supply fluctuations. Additionally, the output response is exceptionally fast, with a turn-on delay of just 0.1 ms and a turn-off delay of 1.0 ms. Therefore, you can rely on the 1769-OB16 for time-sensitive control tasks that demand precise and repeatable switching.

Leakage Current: 1.0 mA @ 26.4V DC
On-State Voltage Drop: 1.0V (max) at 1.0 mA
Wire Size (Solid): 22‑14 AWG
Wire Size (Stranded): 22‑16 AWG
Each output point is protected by IEC Class 2 reinforced insulation, guarding against voltages as high as 75V DC. Meanwhile, the module's status indicators provide clear visual feedback for each channel, simplifying diagnostics and reducing troubleshooting time.
The 1769‑OB16 offers two standard mounting options for convenient installation. Specifically, you can mount it on a DIN rail or directly onto a panel using M4 or #8 panhead screws. This flexibility enables quick integration into new or existing control cabinets. The module occupies a single slot width within a CompactLogix chassis, making it an excellent choice for space-constrained applications.
Moreover, its physical dimensions are compact: 4.65 x 1.38 x 3.43 inches (118 x 35 x 87 mm). The unit weighs approximately 0.61 lb (280 g), which contributes to its lightweight and easy handling. Additionally, it operates within a temperature range of 0 to 60°C and supports relative humidity from 5% to 95% (non-condensing). The module also withstands shocks of up to 30 g, ensuring durability in rugged industrial settings. This module is available in both Series A and Series B, and both revisions maintain full compatibility with the same controller platforms.
Installation and System Integration
When integrating the 1769‑OB16 into a CompactLogix system, you must observe the power supply distance rating. Specifically, this module should not be installed more than eight modules away from the power supply unit. This rule ensures proper bus communication and reliable power distribution across the entire assembly.
For MicroLogix 1500 systems, installation is straightforward. You simply place the 1769-OB16 module beside the base unit and connect it via the provided ribbon cable to establish the communication bus. Additionally, this module is compatible with all 1769 CompactLogix power supplies, including the 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. The module ships with a terminal block, part number 1769-RTBN18, which simplifies field wiring.
Meanwhile, system configuration parameters—such as module inhibition, packet interval, slot assignment, and revision number—are managed through the programming software (e.g., RSLogix 5000 or Studio 5000). Therefore, careful verification of these settings during initial setup will ensure seamless communication with the controller. For proper cooling, maintain at least 2 inches (50 mm) of space between the module and any adjacent equipment. Always disconnect power before installation and follow standard electrostatic discharge (ESD) prevention procedures.
The 1769‑OB16 is particularly well-suited for driving DC loads across diverse industrial sectors. Typical applications include:
Activating DC solenoids and valves
Controlling DC contactors and relays
Switching pilot lights and indicator panels
Energizing DC motor starters
Interfacing with programmable controllers in manufacturing lines
Driving interposing relays for AC load control
Because of its solid-state design, it offers high switching reliability, fast response times, and long operational life compared to mechanical relays. Furthermore, its ability to handle surge currents makes it suitable for loads with high inrush characteristics.
