Allen-Bradley 1762-OB16 24VDC Output Module

Allen‑Bradley 1762‑OB16 16‑Point Digital Output Module

The 1762‑OB16 from Allen‑Bradley is a high‑density discrete output module designed for demanding control applications. Specifically, it provides sixteen sourcing outputs rated for 24V DC operation. Furthermore, it is fully compatible with the MicroLogix 1100, 1200, and 1400 programmable controllers. Therefore, it delivers robust performance for energizing solenoids, pilot lamps, motor starters, and other actuators. Meanwhile, its solid‑state design ensures long service life with minimal maintenance.

Key Technical Specifications

The 1762‑OB16 operates within a voltage range of 20.4 to 26.4V DC. Additionally, it draws a maximum bus current of only 175 mA at 5V DC, which minimizes the load on the system power supply. Moreover, its solid‑state circuitry guarantees fast signal response. For instance, the turn‑on delay is just 0.1 ms, while the turn‑off delay is 1.0 ms. Besides these switching speeds, each output point supports a continuous current of 1.0 A at 30 °C (86 °F) and 0.5 A at 55 °C (131 °F). Consequently, the module can handle a surge current of up to 2.0 A for 10 ms, making it particularly suitable for loads with high inrush currents.

Installation and Compatibility

You can mount the 1762‑OB16 on a standard 35 mm DIN rail or directly onto a panel. First, ensure you maintain at least 2 inches (50.8 mm) of clearance on all sides for adequate ventilation. Next, secure the module using the built‑in mounting clips. Additionally, this module supports different expansion limits depending on the controller. For example, you can install up to four modules with a MicroLogix 1100, six with a MicroLogix 1200, and seven with a MicroLogix 1400. Furthermore, the power supply distance rating is six modules. Therefore, you must not place it more than six modules away from the power supply. However, if you need more than six modules, you can add an additional power supply in between.

Environmental and Mechanical Ratings

This module offers reliable operation across a wide range of industrial environments. Specifically, it features an IP20 enclosure and carries a Class I, Division 2 hazardous location rating. Moreover, the operating temperature range is 0 to 55 °C, while storage temperatures can extend from -40 to 65 °C. In addition, it is designed to withstand operating shock up to 30G and vibration from 10 to 500 Hz at 5G. As a result, the 1762‑OB16 performs consistently even in demanding factory floor conditions. Meanwhile, the module remains lightweight at just 0.52 lbs, which simplifies handling during installation.

Typical Applications

The 1762‑OB16 excels in a variety of control scenarios. For instance, it is commonly used to drive solenoid valves in pneumatic systems. Additionally, it can energize pilot lamps and audible alarms such as horns and buzzers. Furthermore, many engineers choose this module for controlling motor starter coils and small relay banks. Therefore, it serves as a versatile building block for machine control, conveyor systems, and packaging equipment. Consequently, the 1762‑OB16 helps you expand your MicroLogix system without replacing the existing controller.

Frequently Asked Questions (FAQ)

1. Which controllers are compatible with the 1762‑OB16?
This module works seamlessly with the MicroLogix 1100, 1200, and 1400 programmable logic controllers. However, it does not support the MicroLogix 1000 series.

2. What is the maximum number of 1762‑OB16 modules I can use?
The number varies by controller. Specifically, you can use up to 4 with a MicroLogix 1100, 6 with a MicroLogix 1200, and 7 with a MicroLogix 1400.

3. What is the current rating per output point on the 1762‑OB16?
Each point supports 1.0 A at 30 °C and 0.5 A at 55 °C continuously. Additionally, the module handles a 2.0 A surge current for 10 ms per point.

4. Can the 1762‑OB16 be mounted on a DIN rail?
Yes, it supports standard 35 mm DIN rail mounting. Furthermore, a DIN rail end anchor is recommended for high‑vibration environments to prevent loosening.

5. What is the signal delay time for the 1762‑OB16 outputs?
The turn‑on delay is 0.1 ms, and the turn‑off delay is 1.0 ms. Therefore, it responds quickly enough for most high‑speed control applications, including sorting and indexing equipment.
