Mitsubishi AC80TB 32-Point Digital I/O Module for MELSEC-F FX2N Series

The Mitsubishi AC80TB (AC80TB) is a combined digital input and output module designed for Mitsubishi Electric MELSEC-F series programmable logic controllers, specifically the FX2N series. This discontinued mixed I/O unit provides a total of 32 digital input and output channels, functioning as an equivalent replacement for the FX2N-32ES module. The hardware configuration integrates 16 digital inputs rated for 24 V DC operation alongside 16 AC triac digital outputs, enabling reliable discrete signal acquisition and AC load switching within industrial automation systems. Engineered to expand the input and output capacity of FX2N controller setups, the AC80TB delivers seamless integration with compatible PLC base units. The combination of 24 V DC logic inputs and solid-state AC triac switching outputs makes this module well suited for machine automation, packaging machinery, material handling systems, and assembly lines requiring compact signal conditioning. Its robust construction ensures reliable long-term operation and electrical isolation across diverse factory floor environments.
