Allen-Bradley 1756-IB16 Digital DC Input Module

Product Description

The Allen-Bradley 1756-IB16 is a ControlLogix series 16-point digital DC input module, designed for industrial automation applications. It provides reliable signal acquisition from field devices such as push buttons, limit switches, proximity sensors, and relay contacts. The module converts these signals into digital inputs for PLC (Programmable Logic Controller) or DCS (Distributed Control System) processing. With high noise immunity and wide voltage input range (10-31V DC), it ensures stable operation in harsh industrial environments.

Key Features & Advantages

• 16-Channel DC Input – Supports 16 discrete digital inputs for flexible system integration.

• Wide Voltage Range (10-31V DC) – Compatible with various industrial sensors and switches.

• High Noise Immunity – Built-in filtering, reverse polarity protection, and optical isolation (250V continuous between groups) to prevent interference.

• LED Status Indicators – Provides real-time monitoring of input and communication status for easy troubleshooting.

• Compact & Robust Design – Suitable for ControlLogix chassis mounting, ensuring durability in industrial settings.

• Compliance with Industry Standards – Certified by CE, CSA, UL, GOST, and more, ensuring global compatibility.

Technical Specifications

Applications

The 1756-IB16 is widely used in industries requiring precise digital signal acquisition, including:

• Manufacturing Automation – Machine control, assembly line monitoring.

• Energy & Power Systems – Monitoring relay status in substations.

• Building Automation – Elevator control, safety interlock systems.

• Water & Wastewater Treatment – Pump station monitoring, valve position feedback.

• Transportation Systems – Signal acquisition in railway and traffic control.

Precautions

• Ensure proper wiring and grounding to avoid electrical noise interference.

• Verify input voltage compatibility (10-31V DC) before installation.

• Avoid mixing different voltage levels on the same module to prevent damage.

• Follow ESD (Electrostatic Discharge) protection guidelines during handling.

• For high-noise environments, consider shielded cables for signal integrity.
