Allen-Bradley 1794-IV16 Flex I/O 16-Point DC Input Module

Product Overview

The Allen-Bradley 1794-IV16 is a reliable input module from the Flex I/O series, designed to handle 16 nonisolated sourcing inputs. It operates within a precise voltage range, making it a versatile choice for various industrial automation tasks. This module ensures accurate signal processing and efficient performance in demanding environments.

Technical Specifications

The 1794-IV16 features a minimum on-state voltage of 10V DC, a nominal on-state voltage of 24V DC, and a maximum on-state voltage of 31.2V DC. It handles a minimum on-state current of 2.0 mA, a nominal on-state current of 8.0 mA at 24V DC, and a maximum on-state current of 11.0 mA. The module has a maximum off-state voltage of 5V DC and a minimum off-state current of 1.5 mA. Input impedance is 4.7 kΩ, and power dissipation reaches 5.7 W at 31.2V DC. These specs ensure stable and predictable signal control.

Industry Applications

In manufacturing lines, the 1794-IV16 monitors sensor inputs for conveyor systems, ensuring precise material flow. In process control, it reads discrete signals from valves and actuators, supporting automated batch operations. Its robust current handling and wide voltage range make it suitable for harsh industrial settings.

Installation & Setup Guidance

Mount the 1794-IV16 securely on a DIN rail within the Flex I/O chassis. Connect sourcing inputs to the terminal block, ensuring wiring matches the nominal 24V DC supply. Verify that off-state voltages remain below 5V DC to avoid false triggers. Use proper grounding to minimize electrical noise.

Maintenance & Reliability

Periodically inspect the module for dust accumulation and loose connections. Check input signals with a multimeter to confirm on-state and off-state thresholds. The module's 5.7W dissipation at max voltage requires adequate ventilation. Regular testing extends service life and reduces downtime.

Selection Guide & Purchasing Advice

When ordering the 1794-IV16, verify compatibility with your Flex I/O backplane and controller. Ensure your power supply meets the 24V DC nominal requirement. For current availability and lifecycle status, contact BluePLC Industrial. They provide genuine Allen-Bradley parts and expert support.
