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
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.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
