Product Details
Product Overview
The Allen Bradley 1756-OW16IK serves as a high-density, individually isolated relay output module for the ControlLogix platform. This module provides 16 independent N.O. (Normally Open) contacts, allowing the control system to switch diverse load voltages and polarities within a single chassis slot. The "K" suffix indicates a conformal coating, which protects the internal circuitry from corrosive atmospheric contaminants. We supply this unit as 100% Brand New original factory equipment, ensuring maximum contact life and circuit integrity for your mission-critical switching applications.

Engineering Advantages
-
Individual Channel Isolation: Each of the 16 outputs maintains electrical isolation from the others. This architecture permits the simultaneous control of multiple voltage sources (e.g., mixing 120V AC and 24V DC) on one module, eliminating the need for interposing relays and reducing panel space requirements.
-
Conformal Coating (K-Suffix): The specialized protective coating shields the PCB from moisture, salt spray, and chemical vapors. This makes the 1756-OW16IK the ideal choice for wastewater treatment, oil and gas, and chemical processing facilities where standard modules might suffer from premature corrosion.
-
Broad Voltage Versatility: This module switches a wide operating range, from low-voltage 5V DC logic up to 265V AC power circuits. The relays handle diverse loads including solenoids, motor starters, and indicators, providing a universal interface for field devices.
-
Integrated Diagnostics: The module reports field-side power status and point-level state to the controller. This real-time feedback accelerates troubleshooting by identifying blown fuses or power losses directly through the Studio 5000 software interface.
FAQs
-
Can the 1756-OW16IK replace a standard 1756-OW16I module?
Yes. The 1756-OW16IK functions exactly like the 1756-OW16I but adds conformal coating for environmental protection. It utilizes the same profile in Studio 5000, allowing for a direct physical and logical drop-in replacement.
-
Which Removable Terminal Block (RTB) should I use?
This module requires a 36-pin RTB. You can use the 1756-TBCH (Cage Clamp) for secure manual wiring or the 1756-TBS6H (Spring Clamp) for high-vibration environments where screw-less termination is preferred.
-
Does this module support "Normally Closed" (N.C.) configurations?
The 1756-OW16IK provides Normally Open (N.O.) contacts only. If your application requires N.C. logic, you must handle the inversion within the PLC ladder logic or utilize an external interposing relay.
-

Tech & Buying Guide
Implementing FIFO and LIFO Data Sequencing in PLC Programming
Data management serves as a cornerstone of modern industrial automation. Whether tracking materials on a conveyor or managing batch sequences in a process, engineers frequently rely on sequential logic. Two primary structures—First-In-First-Out (FIFO) and Last-In-First-Out (LIFO)—form the bedrock of this data handling. Mastering these blocks allows programmers to optimize complex machine operations efficiently.
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
