The 1794-OB8EP delivers eight digital sourcing outputs
for precise DC load control in your control system.
It integrates an electronic fuse to disconnect loads
instantly when a fault condition occurs.
This feature protects your field devices and wiring
from damage due to overcurrent or short circuits.
The module directly reduces costly downtime events.
Allen-Bradley 1794-OB8EP: The Intelligent Choice for Procurement
Procurement managers select this module for its
enhanced reliability and built-in circuit protection.
The electronic fuse eliminates the need for external
fuses, reducing panel components and wiring complexity.
This design saves valuable cabinet space and cuts
installation labor costs significantly.
You can source this module to drive a wide range
of 24V DC actuators, valves, and indicator lights.
Each output channel handles up to
2A per Output.
The module supports a maximum module current of 10A.
It operates within a voltage range of 19.2 to 31.2V DC.
This ensures stable performance even with line fluctuations.
This module uses a 1794-TB3 or other compatible
terminal base for quick, tool-free field wiring.
The primary benefit is the integrated fault management.
When a short circuit occurs on any output channel,
the electronic fuse activates to isolate the fault.
This action prevents a single channel failure from
bringing down the entire control system.
This modular approach improves overall system uptime.
Engineers appreciate the fast 0.1ms output delay
from Off-to-On and On-to-Off transitions.
This speed ensures precise timing for critical processes.
Expert Technical Evaluation of the 1794-OB8EP
This module provides robust electrical performance.
It has a maximum on-state voltage drop of 0.2V DC.
This low drop ensures efficient power delivery to loads.
The off-state leakage current is a maximum of 0.5mA.
This prevents accidental activation of sensitive loads.
The module draws 73mA from the FlexBus at 5V DC.
Its maximum power dissipation is 5.5W at 31.2V DC.
This generates a thermal load of 18.8 BTU/hr.
This low dissipation allows for dense cabinet layouts.
The 1794-OB8EP uses a 50V continuous isolation barrier.
This protects the backplane from field-side voltage surges.
The module installs directly onto a DIN rail.
You can connect it to multiple network adapters.
Supported communication options include ControlNet,
DeviceNet, and EtherNet/IP networks.
This flexibility allows integration into any Rockwell system.
Sixteen yellow LED indicators show the status of
each output channel for quick troubleshooting.
The module supports hot insertion and removal under power.
This feature eliminates the need to restart the system.
An XT version is available for extreme environments.
This reduces replacement and maintenance costs.
