Mitsubishi AY42 Programmable Logic Controller for MELSEC-F FX3S Series

The Mitsubishi AY42 (AY42) is an entry-level programmable logic controller central processing unit with integrated inputs and outputs, engineered for compact automation and machine control within the MELSEC-F FX3S series. Equivalent to the FX3S14MTESS configuration, this controller provides an integrated total of 14 digital I/O points, consisting of 8 digital inputs and 6 digital outputs. The input section operates on 24 V DC with selectable sink or source (negative or positive) logic, ensuring flexible integration with various field switches and sensors. The output section features 6 transistor digital outputs operating from 5 to 30 V DC with positive logic, delivering a maximum load rating of 500 mA and a rapid response time of 0.2 ms. Designed for reliable operation across industrial environments, the unit is powered by a standard AC supply of 100 to 240 V AC, supporting 120 V, 208 V, 220 V, and 230 V AC electrical systems. It incorporates an internal EEPROM memory with a program capacity of 4,000 steps to maintain sequence programs securely. This compact controller is utilized in diverse automated machinery, handling sequence logic and real-time control across small-scale industrial manufacturing and processing equipment.
