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
Demystifying Programmable Logic Controllers: Comprehensive Guide to PLC Classification and Selection in Industrial Automation
Modern industrial automation heavily relies on Programmable Logic Controllers (PLCs) to drive factory floor efficiency. Over my 15 years as an industrial automation expert working with DCS, TSI, and control systems, I have seen PLCs evolve into the central nervous system of modern manufacturing. Selecting the right controller requires a deep understanding of PLC types based on physical size, hardware architecture, and power supply configurations.
Comprehensive Guide to PLC Types in Modern Industrial Automation
Modern industrial automation relies on programmable logic controllers to govern critical factory operations. System integrators classify PLCs based on scale, hardware architecture, and power supply design. Understanding these core categories enables automation engineers to select the right control system architecture. Consequently, proper hardware selection optimizes performance while minimizing long-term operational costs.
Demystifying the DDE Protocol in Legacy Industrial Automation Systems
Modern control systems rely heavily on seamless interprocess communication to exchange operational data between software programs. Microsoft first introduced the Dynamic Data Exchange (DDE) protocol in 1987 to enable real-time data sharing. In factory automation, DDE served as an early bridge between control software and Windows desktop applications. Therefore, understanding DDE mechanics provides crucial insights into how legacy industrial networks established software-level connectivity.
