Product Details
Product Overview
The 1771-IQ16 provides high-density digital sensing for the Allen-Bradley PLC-5 platform. This module interfaces 16 discrete DC input signals from field devices—such as limit switches, photoelectric sensors, and proximity sensors—directly to the processor. It supports a wide operating range of 10-32V DC, making it compatible with standard 24V DC industrial control circuits. We supply this unit as 100% Brand New and factory-original, ensuring your legacy 1771 Universal I/O chassis maintains peak performance despite the manufacturer's 2020 discontinuation.

Engineering Advantages
-
Superior Signal Isolation: The 1771-IQ16 features robust electrical isolation between the field-side inputs and the logic-side backplane. This prevents high-voltage spikes or ground loops from damaging the PLC processor, which is a critical advantage in large-scale plants with long wire runs.
-
Flexible Voltage Compatibility: The 10-32V DC range accommodates fluctuating power supplies. It ensures reliable "ON" state detection even during significant voltage drops in busy industrial DC grids, effectively eliminating intermittent signal faults.
-
High-Density Rack Efficiency: By packing 16 inputs into a single 1771 slot, this module maximizes your chassis real estate. This allows for system expansion or complex machine control without the need to purchase additional expensive I/O racks.
-
Drop-in Replacement Integrity: As a 100% Brand New unit, the 1771-IQ16 requires no software changes or hardware modifications. You simply slide it into the existing slot and reconnect the wiring arm to restore full machine functionality instantly.
FAQs
-
Does the 1771-IQ16 require a specific wiring arm?
Yes. You typically pair this module with the 1771-WN or 1771-WH wiring arm. The arm allows you to swap modules without disconnecting individual field wires, which significantly reduces downtime during maintenance.
-
Can I use this module with 12V DC systems?
Yes. The 1771-IQ16 activates at 10V DC, making it perfectly suitable for both 12V DC and standard 24V DC control architectures.
-
Since this part is discontinued, how do you guarantee its "Brand New" status?
We source these modules from climate-controlled, factory-sealed surplus inventories. Every 1771-IQ16 arrives in its original Allen-Bradley box with factory seals intact, ensuring the internal capacitors and components have zero operational wear.
-
What is the difference between this and non-isolated modules?
Non-isolated modules often share a common ground. The isolated design of the 1771-IQ16 provides a higher layer of protection for the CPU, making it the preferred choice for environments with high electromagnetic interference (EMI) or varying ground potentials.

Tech & Buying Guide
Ensuring Operational Continuity: The Strategic Value of Redundant Automation Systems
In modern industrial landscapes, unplanned downtime is the ultimate adversary. For sectors relying on complex PLC and DCS architectures, a single hardware failure can trigger catastrophic production losses. Therefore, implementing redundant automation systems is no longer a luxury; it is a fundamental requirement for mission-critical operations. In this article, I analyze why redundancy remains the backbone of reliable industrial infrastructure.
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
Preventing Spurious Trips in Emergency Stop Systems: A Technical Guide
In industrial automation, the Emergency Stop (E-Stop) pushbutton is the ultimate safety line. However, relying on a single Normally-Closed (NC) contact can sometimes lead to unexpected spurious trips. As a control systems engineer, I have seen these nuisance trips halt entire production lines, causing significant downtime. Understanding why these components fail and how to implement robust architecture is essential for any reliable DCS or PLC-based safety system.
