The Allen-Bradley 1756-OB8 is a ControlLogix digital DC output module developed by Rockwell Automation.
It provides eight sourcing output channels arranged in two groups of four, operating within a voltage range of 10–30 VDC (nominal 24 VDC).
Each channel can deliver up to 1 Ampere of output current at 60°C, making it suitable for standard industrial control and discrete output applications.
The 1756-OB8 module is compatible with all ControlLogix chassis and uses either the 1756-TBNH or 1756-TBSH removable terminal block (RTB) for field wiring connections.
This module offers LED indicators for channel status and robust electronic protection for reliable operation in industrial environments.
