Allen-Bradley 1794-IV16 Flex I/O Input Module

Description

The Allen-Bradley 1794-IV16 Flex I/O Input Module is a high-performance, high-density digital input unit belonging to the Allen-Bradley Flex I/O distributed I/O system. It serves as a core component for connecting field devices to upper-level control systems, converting discrete signals from devices like buttons, limit switches, proximity switches, and photoelectric sensors into logic level signals recognizable by PLC or DCS systems, enabling real-time industrial process monitoring and control.

Key technical specifications include a compact form factor measuring 23mm x 100mm x 120mm, a weight of approximately 0.4kg, and firmware version V2.2.0. It features 24 input/16 output points, a 32kbyte program capacity, and a product type identifier of CPUST30DC/DC/DC. Designed with a modular structure, it supports tool-free assembly onto DIN rails, allowing flexible integration into complex automation architectures via compatible adapters for networks like EtherNet/IP, ControlNet, and DeviceNet.

Built for industrial environments, it operates in temperatures ranging from -20 degrees Celsius to 70 degrees Celsius, with isolated input channels to resist electrical noise interference, ensuring stable signal transmission. It supports both sourcing and sinking wiring configurations, making it suitable for diverse applications in manufacturing, energy, chemical processing, and water treatment sectors.
