The Allen-Bradley 1756-OB16IEF is a highly efficient ControlLogix DC digital output module designed for fast peer-control with digitally isolated outputs. It features 16 individually isolated outputs and responds to system transitions in under 25 microseconds, making it ideal for time-sensitive applications. The module is electronically fused per point for enhanced protection and includes status indicators for both diagnostic and I/O feedback. Required components for installation include a 1756-TBS6H or 1756-TBCH removable terminal block housing. Notable functions include fault reporting and configurable point-level output states, enabling customization for various operational needs. With compatibility as a CIP Sync slave device, this output module requires an external master clock for network synchronization. Engineered with current draw efficiencies and robust isolation, it supports a voltage range of 10-30V DC, while maintaining rigorous standards for inrush current, fault-mode durations, and PWM parameters.
