Short Description
Description:
The 1756-OB8EI is an 8-point digital output module for the ControlLogix platform that is intended to control field devices operating at 24V DC.
Each output channel is separately isolated, providing strong protection against electrical noise and enabling for flexible wiring across multiple voltage ranges.
This module is perfect for controlling DC actuators like solenoids, relays, and contactors.
It has increased electronic protection, including short-circuit and overload detection, and output status monitoring for better diagnostics and system reliability.
