Short Description
Description:
The 1756-PBXTR is a ControlLogix-compatible DC redundant power supply module designed for extended temperature settings.
It delivers regulated DC power to ControlLogix chassis components and allows redundant power configurations, ensuring high availability in severe industrial environments.
This module is suited for use in outdoor installations, distant facilities, and harsh settings where typical temperature ranges are inadequate.
It operates in tandem with another 1756-PBXTR to provide a smooth power switchover without affecting system performance.
