Allen Bradley 1769-OB16P Protected Output Module

Product Description

The 1769-OB16P (1769-OB16P) is a high-density digital output module designed for the Allen-Bradley CompactLogix and MicroLogix 1500 systems. This 16-channel sourcing module provides 24V DC power to field loads such as solenoids, relays, and indicators. A standout feature of the "P" designation is its integrated electronic protection, which helps safeguard the module from short circuits and overload conditions. Engineered for high-availability industrial applications, the 1769-OB16P balances high current capacity with robust diagnostic capabilities in a compact 35mm form factor.

Key Engineering Features

The 1769-OB16P (1769-OB16P) is optimized for precision control and hardware longevity:

• Electronic Short-Circuit Protection: The module is designed to detect and react to short circuits or excessive current draws on a per-group basis, preventing permanent damage to the internal circuitry and reducing downtime.

• Thermal Management: It offers impressive current density, capable of supporting up to 8.0 A per module at lower ambient temperatures, making it suitable for driving multiple heavy-duty DC loads simultaneously.

• Rapid Response Times: With an "On" delay of just 1.0 ms, the module is ideal for high-speed sorting, packaging, and assembly applications where timing is critical.

• Efficient Heat Dissipation: Designed to dissipate a maximum of 2.69 W, the module maintains a cool operating profile even when fully loaded, extending the lifespan of adjacent components in the I/O rack.

• Simplified Maintenance: Compatible with the 1769-RTBN18 removable terminal block, allowing for "plug-and-play" module replacement without re-wiring the field side.
