Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-OH8I is a ControlLogix® module within the Allen-Bradley 1756 platform. It provides eight individually isolated digital DC outputs (sink/source) rated at 125 V DC, typically used in automated control systems to switch DC loads such as solenoids, lamps, or contactors. The module installs in a ControlLogix chassis, interfaces via the backplane, and is common in industrial applications requiring channel isolation and high output current capacity. 1756-OH8I facilitates coordinated digital output control in manufacturing, material handling, or process systems.
Best Suited For
- ControlLogix racks requiring 125 V DC isolated switching
- Applications needing individual channel isolation
- High-current DC load switching (up to 2 A per channel)
