Short Description
Description:
The Allen-Bradley 1756-OB16IS is a high-speed, isolated digital output module intended for use with ControlLogix® systems.
It has 16 individually separated source outputs, which allows for more flexible wiring and better protection against electrical problems.
CIP Sync allows you to regulate and synchronize each output individually, making it suitable for motion control, machine coordination, and time-critical automation applications.
This module has a 12/24V DC output, reliable current handling, and customizable fault states.
Its isolated architecture enhances noise immunity and system stability, particularly in settings with several signal types or severe electromagnetic interference.
16 sourcing DC outputs (each isolated).
Supports 10-30V DC and is ideal for 12/24V systems.
CIP Sync is activated for precise timing and synchronization.
Hot-swappable, resulting in minimal downtime.
Configurable fault states (Hold, On, and Off).
Suitable for high-speed, deterministic control applications.
