Mitsubishi FX5-16ET-ESS Digital I/O Module for FX Series

The Mitsubishi FX5-16ET-ESS (FX5-16ET-ESS) is a combined digital input and output module designed for use with Mitsubishi Electric MELSEC-F FX series programmable logic controller systems. This extension unit expands the automation capacity of compatible PLC configurations by providing a total of 16 digital input and output channels. The hardware configuration integrates 8 digital inputs rated for 24 V DC operation alongside 8 digital transistor outputs configured for 24 V DC source type switching. Engineered to interface directly with FX series base controllers, the FX5-16ET-ESS enables reliable signal processing and actuator control across a variety of industrial automation systems, including material handling, packaging machinery, assembly lines, and discrete manufacturing processes. The module processes binary field signals from sensors, switches, and pushbuttons while delivering fast switching capabilities to drive downstream control relays, indicators, and electronic actuators. With its integrated input and output layout, this expansion module optimizes panel space and simplifies field wiring in compact automation enclosures requiring distributed digital I/O expansion.
