Product Introduction
When output protection is critical, the Allen-Bradley 1769-OB16P solid-state DC output module delivers robust performance. This module is part of the 1769 Compact I/O family, designed for use with CompactLogix and MicroLogix 1500 controllers. The 1769-OB16P features sixteen (16) protected output channels in a single group, providing electronic protection against overloads. It operates at a 20.4-26.4VDC output voltage range, making it suitable for demanding industrial environments. The 1769-OB16P ensures reliable switching with an OFF to ON delay of 1 ms and ON to OFF delay of 2 ms, minimizing signal hesitation.
Technical Specifications Breakdown
The Allen-Bradley 1769-OB16P offers precise performance metrics. Key specifications include:
- Outputs: Sixteen (16) outputs
- Output Voltage: 24VDC (range 20.4-26.4VDC)
- Backplane Current at 5.1V: 160 mA
- Continuous current per point: 0.50 A @ 30°C, 1.0 A @ 55°C
- Continuous current per module, max: 4.0 A @ 30°C, 8.0 A @ 55°C
- Off-state leakage current: 1.0 mA @ 26.4V DC
- Output delay: OFF to ON 1 ms, ON to OFF 2 ms
These specs ensure the 1769-OB16P handles moderate loads with efficiency. The integrated electronic protection prevents damage from short circuits or overcurrent, a key advantage in failure-prone environments.
Industry Applications
The Allen-Bradley 1769-OB16P excels in applications requiring high reliability. Typical uses include controlling solenoid valves, indicator lights, and small motor starters in manufacturing lines. In a packaging plant, the 1769-OB16P can drive multiple actuators with its sixteen outputs, benefiting from the electronic protection that reduces downtime from blown fuses. Its compatibility with CompactLogix and MicroLogix 1500 makes integration straightforward.
Installation & Setup Guidance
Installing the Allen-Bradley 1769-OB16P is simple. Use a 1769-RTB18 Removable Terminal Block (sold separately) for wiring. Wire solid conductors of 22 to 14 AWG. The module must be placed within eight modules of the power supply to maintain proper operation. For systems requiring more modules, add a 1769-PA2, 1769-PB2, or similar power supply. Ensure the power supply distance rating is not exceeded to maintain a valid CompactLogix configuration.
Maintenance & Reliability
Routine inspection of the Allen-Bradley 1769-OB16P helps ensure longevity. Check for debris on the terminal block and verify all output LEDs function. The solid-state design offers high reliability with no moving parts. Operating within the specified temperature range (up to 55°C) ensures consistent performance. The 1769-OB16P's electronic protection reduces the risk of failure from overcurrent, lowering maintenance costs over time.
Selection Guide & Purchasing Advice
When selecting the Allen-Bradley 1769-OB16P, verify your controller compatibility. It works with CompactLogix and MicroLogix 1500. Consider the number of outputs needed – sixteen points are ideal for mid-scale applications. For remote I/O, use expansion configurations. Purchase from UBEST Automation (ubest101) to ensure genuine parts and fast shipping. Always double-check the 1769-OB16P catalog number to match your system requirements.
