Short Description
Description:
The Allen-Bradley 1756-OB16D is a high-performance digital output module intended for use with ControlLogix® programmable automation systems.
It has 16 source outputs that operate at 24V DC and features comprehensive diagnostic tools to monitor the health and state of each output.
This module is suited for industrial applications that require real-time defect detection, system dependability, and predictive maintenance.
It reduces downtime by detecting issues including open loads, short circuits, and overcurrent conditions, which are then sent directly to the controller.
16 digital outputs sourced from positive logic.
It operates at 24V DC and can deliver up to 1A per output.
Point-level diagnostics to improve fault detection.
LED indicators display channel status and fault circumstances.
Hot-swappable for convenient maintenance.
Compatible with the ControlLogix chassis and terminal blocks.
