Information About 1746-OBP16

The 1746-OBP16 is a Sixteen (16) channel Discrete Output module from the SLC 500 product family. It provides 24VDC output with integrated fuse for short-circuit protection.

This module occupies single slot of an SLC 500 chassis. It is compatible with fixed or modular style hardware.

The 1746-OBP16 features an integrated fuse that protects the module from channel short-circuit and overload current. The E-FEUSE LED that is provided in the front panel of the module will illuminate to indicate presence of such condition. Other channels will continue to operate as the electronic protection are individual for each channel.

It is considered a channel shutdown when the error has been detected. To allow the channel to recover from the fault condition, the SLC 500 system power must be removed and the actual error must be corrected. Once the actual source of error has been corrected, the system power may be applied, and the module automatically reset and resumes providing control output. This automatic fault recovery must be taken into consideration as part of the system’s fail-safe operating conditions.

Compatible replacement fuse for the integrated electronic fuse are Littelfuse #322010,10A or #332010,10A. This fuse component is to maintain UL/CSA rating. Allen-Bradley’s fuse catalog number is 1746-OBP16 which is comprised of Five (5) fuse per kit. This fuse may be easily replaced however, it requires pulling out of module from the chassis.

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.
