The Allen-Bradley 1769-OB16P is a high-performance digital output module from Rockwell Automation's 1769 Compact I/O family. For starters, this module provides sixteen (16) sourcing outputs in a single group, operating at a nominal 24 Volts DC. Specifically, the module is designed for use with CompactLogix and MicroLogix 1500 controllers, serving as a reliable interface for controlling actuators, indicators, and other field devices. Meanwhile, its solid-state construction ensures long-term durability and fast switching speeds. Therefore, this module is an excellent choice for demanding industrial automation environments.
To begin with, this module operates within a voltage range of 20.4 to 26.4VDC. In addition, its outputs have an OFF to ON delay of just 1.0 ms and an ON to OFF delay of 2.0 ms, enabling highly precise control. Moreover, the 1769-OB16P draws a backplane current of 160 mA at 5.1 Volts. Notably, the off-state leakage current is a minimal 1.0 mA at 26.4V DC, which helps prevent false triggering of connected loads. For instance, this low leakage is particularly beneficial when driving high-impedance input devices.
Furthermore, the continuous current per point is rated at 0.5 A at 60 °C and 1.0 A at 30 °C. Similarly, the total continuous current per module is 4.0 A at 60 °C and 8.0 A at 30 °C. Meanwhile, the surge current rating reaches 2.0 A for 10 ms, and this surge is repeatable every 1 second. Additionally, the maximum on-state voltage drop is only 0.5 Volts, which minimizes power loss and heat generation. Consequently, the module's heat dissipation is rated at 2.69 W, ensuring efficient thermal management within the control cabinet.
First, this output module comes with integrated electronic protection, safeguarding the outputs against overcurrent and short-circuit conditions. Besides that, it features IEC Class 2 reinforced insulation, providing protection against voltages up to 75 Volts DC. For field wiring connections, however, the 1769-OB16P requires a separate 1769-RTB18 removable terminal block. Likewise, you will need a 1769-RL1 door label and a 1769-RD door for proper identification and protection. Therefore, these accessories are available as individual ordering kits, not included with the module itself.
Next, the power supply distance rating for the 1769-OB16P is eight (8) modules. In other words, this rating defines the maximum allowable distance between this module and the power supply within the CompactLogix assembly. Exceeding this distance, however, may compromise system performance and configuration validity. For this reason, larger systems that require additional power can benefit from supplementary power supply modules. For example, you can install the 1769-PA2, 1769-PB2, 1769-PA4, or 1769-PB4 along the assembly to extend the power capacity beyond the primary supply's capability.
Turning to physical dimensions, the 1769-OB16P measures approximately 4.65 x 1.38 x 3.43 inches. Moreover, it has a lightweight design, weighing only 0.56 pounds. In terms of wiring, the module supports solid copper wire sizes from 22 to 14 AWG, making it versatile for various installation requirements. Furthermore, its operating temperature range ensures reliable performance in typical industrial environments. Nevertheless, users should observe proper derating curves when operating at elevated temperatures, as reflected in the current specifications mentioned earlier.
When installing the 1769-OB16P, the process is relatively straightforward. First, ensure the system power is disconnected before any installation work begins. Next, slide the module into the desired slot on the CompactLogix or MicroLogix 1500 DIN rail or panel. After that, secure the module by locking the retaining clips firmly into place. Following this, connect the field wiring to the 1769-RTB18 removable terminal block, observing correct polarity for sourcing outputs. Finally, reapply power and configure the module within your Rockwell Automation programming software. For optimal performance, always adhere to the power supply distance rating and observe proper derating curves when operating at elevated temperatures.
