INDUSTRIAL I/O / FLEX I/O
1794-OB8EP
8-Point Electronically Fused 24V DC Sourcing Output Module
The 1794-OB8EP provides eight current-sourcing DC outputs for distributed FLEX I/O installations. Each point includes electronic overcurrent protection, a yellow output-status indicator and a red fault indicator. A fault can be reset at the front pushbutton, through the reset bit, or by cycling backplane power.
8 SOURCING OUTPUTS
19.2...31.2V DC
2.0 A MAX / POINT
Signal and Electrical Profile
Electronic Protection
Outputs are electronically fused. Fault status is returned for points 0...7, and the lower byte of read word 1 must not be used as fault status.		 Fast Switching
Maximum delays are 0.1 ms from OFF to ON and 0.1 ms from ON to OFF.		 Load Capacity
Up to 2.0 A per output and 10.0 A total, including combinations such as eight points at 1.25 A or five at 2.0 A.
Parameter Value
Terminal bases 1794-TB2, TB3, TB3S, TBN, TB3K, TB3SK or TBNK
Surge capability 4 A for 50 ms, repeatable every 3 seconds
Voltage drop / leakage 0.2V DC max / 0.5 mA max
Flexbus current 73 mA at 5V DC
Indicators 8 yellow status and 8 red fault indicators

SYSTEM RELATIONSHIP
1794-OB8EP in the FLEX I/O DC Output Family
Model Output Format Selection Difference
1794-OB8EP 8 sourcing, 2 A per point, 10 A module Electronic fusing, fault feedback and dedicated fault reset behavior.
1794-OB8 8 sourcing, 0.5 A per point, 4 A module Lower current capacity; external fusing is recommended.
1794-OB16P 16 sourcing, 0.5 A per point Higher point density with electronic protection but different current and image size.
Selection point: Match the terminal base, 24V DC field supply, point current, total module current and fault-reset strategy.

1794-OB8EP Buyer FAQ
Can 1794-OB8EP deliver 2 A on all eight outputs together?
No. Each point can reach 2 A, but the module total is limited to 10 A.		 Does 1794-OB8EP need external output fuses?
The outputs are electronically fused; coordinate downstream protection with the actual load and plant practice.
How is an overload cleared on 1794-OB8EP?
Correct the field fault, then use the front reset button, the reset bit, or a backplane power cycle.		 Which terminal bases fit 1794-OB8EP?
Use TB2, TB3, TB3S, TBN, TB3K, TB3SK or TBNK variants as appropriate.
What should be checked before replacing 1794-OB8EP?
Verify sourcing polarity, 19.2...31.2V DC supply, point and total current, keyswitch position 2, terminal base and fault handling.
