Mitsubishi AY70-UL I/O Module for MELSEC PLC Systems

The Mitsubishi AY70-UL (AY70-UL) is an I/O module designed for Mitsubishi programmable logic controller (PLC) systems, providing digital signal interfacing for automated machinery and control systems. Listed in connection with MELSEC-F series platforms such as the FX3S and equivalent to FX3S30MRDS setups, the unit manages field data exchange between external devices and the controller. Key technical specifications include a 24 V DC supply voltage, screw terminal connections for I/O wiring, and communication interfaces featuring a Universal Serial Bus (USB) port and RS-422 connectivity. The housing is designed for standard DIN rail mounting with a width of 100 mm, enabling straightforward installation inside control cabinets. The device provides connection capacity for 30 total I/O points, comprising 16 digital inputs rated at 24 V DC with sink/source logic and 14 digital outputs with normally open relay contacts rated at 2 A for 240 V AC or 30 V DC with a 10 ms response time. It also features 4,000 steps of EEPROM memory capacity. The AY70-UL ensures dependable switching, signal integrity, and process control across manufacturing lines and machinery automation applications.
