Mitsubishi Electric FX1N-24MT-DSS Programmable Controller

The Mitsubishi Electric FX1N-24MT-DSS is a compact programmable logic controller (PLC) designed for discrete logic control and sequencing in industrial automation, commonly installed in control panels and machinery to coordinate sensors and actuators. It provides 24 I/O points (typically 14 inputs and 10 transistor outputs) with 24 VDC input signals and 24 VDC transistor outputs, and supports a power supply of 100–240 VAC or a 24 VDC variant depending on the platform. The FX1N-24MT-DSS includes on-board memory for user logic programs and can be expanded via FX1N expansion I/O modules. Communication options include optional serial or network modules, while status LEDs indicate power, run, error, and I/O activity. Mounting supports DIN-rail or panel configurations, and the unit is intended for industrial operating temperatures. This model is widely used in conveyor systems, packaging machines, material handling equipment, assembly lines, and standalone automated machinery where 24 VDC logic and transistor outputs are suitable for discrete control tasks and sequencing. Common replacements include Mitsubishi FX1N-24MR-ES, FX3S-24MR/DS, and Omron CP1E-N30DR-A.
