Information About 1756-OB16IS
The 1756-OB16IS is part of Rockwell Automation’s ControlLogix series, engineered to support isolated digital output applications requiring precise timing and robust electrical separation. Its design incorporates individually isolated channels to minimize electrical interference between output points, improving system reliability. The module supports scheduled outputs coordinated through CST (Coordinated System Time), enhancing deterministic control in time-critical processes. Typical applications include machine control, process automation, motion coordination, and systems requiring high-integrity DC output signaling.
Key Features
- 16 individually isolated outputs: Reduces channel-to-channel interference and enhances system protection.
- 8 scheduled outputs: Supports CST synchronization for precise timing control.
- 12/24 VDC sink/source capable: Flexible voltage category for diverse installations.
- 10–30 VDC operating range: Suitable for a broad variety of DC control systems.
- Low backplane power draw: Consumes only 350 mA at 5.1 V and 2.5 mA at 24 V.
- High durability: Supports 2 A DC-13SQ pilot duty rating for demanding loads.
- Open-style module: Designed for installation in a 1756 ControlLogix chassis.
- Robust environmental performance: Rated for 60°C operation with industrial shock and vibration tolerance.
The 1756-OB16IS delivers the reliability and precision required for isolated DC output control in advanced automation systems.
