Short Description
Description:
The 1756-OB16DK is a high-performance digital output module designed to work with ControlLogix® 5580 systems.
It has 16 source outputs that run at 24V DC, improved diagnostic capabilities, and conformal coating for increased durability in tough industrial applications.
This module is designed to provide fast switching, real-time defect detection, and reliable output control, making it perfect for demanding applications such as automated manufacturing, material handling, and process control.
There are sixteen sourcing (positive logic) digital outputs.
24V DC operation with up to 2 amps per channel (at 30°C).
Diagnostics for open load, short circuit, and overcurrent detection are all integrated.
LED indicators display channel status and fault circumstances.
Conformal coating protects against moisture and corrosive substances.
Hot-swappable architecture ensures little downtime.
Compatible with the ControlLogix chassis and terminal blocks (1756-TBCH, 1756-TBS6H).
