Allen-Bradley 1794-IM8 Flex I/O Digital Input Module

Description

The Allen-Bradley 1794-IM8 Flex I/O Digital Input Module is a distributed I/O component belonging to the Flex I/O product series, designed as an input interface to integrate field instruments and electrical devices into automated control systems or processes. This sink current input module supports up to 8 DC input devices, making it suitable for connecting equipment like push buttons, limit switches, proximity sensors, float switches, process switches, relay contacts, and contactor auxiliary contacts. Key electrical specifications include a minimum on-state voltage of 10V DC, maximum on-state voltage of 31.2V DC, maximum on-state current of 12.0mA, and maximum off-state voltage of 5V DC. It features flexible network compatibility, supporting communication options such as EtherNet/IP, ControlNet, DeviceNet, and universal remote I/O when paired with compatible Flex I/O communication adapters, with no limit on installation instances when proper mounting requirements are followed. The module’s modular design allows independent selection of I/O, terminal types, and network interfaces; it tool-free assembly enables components to be snapped onto DIN rails and plugged together to form a complete I/O system, delivering cost-effectiveness, flexibility, and reliable performance for distributed automation applications.
