Information About 1746-OBP16

Part of the Allen-Bradley SLC 500 family, the 1746-OBP16 is a sourcing-type DC output module featuring 16 individually protected output points. Each channel delivers 1.0–1.5 A, with a total module capacity of 6.4 A, making it suitable for higher current DC loads such as solenoids, indicator lamps, contactors, and relays. A key feature of this module is its integrated electronic fuse, which provides fast protection against overcurrent and short-circuit events. When a fault is detected, the module triggers a channel shutdown, and an E-FUSE status LED illuminates. This protects adjacent channels and reduces system downtime. Once the issue is corrected, cycling system power restores full module functionality.

Key Features:

  • 16 sourcing-type 24 VDC digital outputs
  • High-current capability per channel
  • Integrated electronic fuse with E-FUSE LED
  • Independent channel protection and shutdown
  • Single-slot SLC 500 installation
  • Fast switching response
  • Ideal for inductive and high-current loads
  • UL/CSA fuse-maintained compliance

The 1746-OBP16 installs in a single slot of the SLC chassis and communicates via the SLC backplane, drawing 250 mA at 5 VDC. It supports up to 14 AWG (2 mm²) signal wiring and provides a fast step response of 60 ms (in) / 2.5 ms (out).

Frequently Asked Questions about 1746-OBP16
Question: What is the function of the 1746-OBP16 module?
Date Update:13/06/2025
Answer:

The Allen-Bradley 1746-OBP16 is a digital DC output module used to control actuators and indicators in industrial automation systems. It provides 16 output channels that deliver DC voltage in a sourcing configuration. This module interfaces with field devices such as relays, solenoids, and indicator lamps. It is designed for use within the SLC 500 platform and supports both modular and fixed chassis systems. With built-in protection features, it ensures safe and reliable switching of DC loads in demanding environments.

Question: What is the voltage output range?
Date Update:13/06/2025
Answer:

The 1746-OBP16 operates in the 20.4 to 26.4 Volts DC range. This voltage range supports standard 24VDC loads common in industrial applications. It ensures proper signal levels for actuators and devices, maintaining stable performance. Operating outside this voltage range may lead to unreliable switching or fault conditions. Always ensure the power supply and load match this range for optimal performance.

Question: Does the module include fuse protection?
Date Update:13/06/2025
Answer:

Yes, the module has integrated electronic fuses for each channel, providing protection from short circuits and overloads. If a channel experiences a fault, its fuse disconnects the output while other channels remain active. An E-FEUSE LED on the module indicates the presence of a fault. To reset, the system power must be cycled after correcting the error. This design enhances system safety and minimizes downtime.

Question: What is the step response time?
Date Update:13/06/2025
Answer:

The 1746-OBP16 features a step response of 60 milliseconds in and 2.5 milliseconds out. This means it responds to output commands quickly, making it suitable for high-speed switching applications. The fast output reaction helps minimize system latency. Input delay ensures signal stability before switching. This timing characteristic is critical for time-sensitive control processes.

Question: What chassis is it compatible with?
Date Update:13/06/2025
Answer:

The 1746-OBP16 is compatible with both fixed and modular chassis from the SLC 500 series. It occupies a single slot in the chassis. It can be used with other SLC I/O, communication, and processor modules. The module integrates seamlessly into existing Allen-Bradley control systems. This compatibility makes it a flexible solution for expansion or upgrades.
