The FX5U-80MT/DSS is engineered to handle complex automation challenges with ease. It features a 24V DC power supply and supports rapid instruction execution with a cycle time of just 34 ns for both LD and MOV commands. Backed by 64K STEPS of FLASH program memory, this Mitsubishi PLC ensures long-term data retention and high-speed logic execution for time-critical industrial processes. Its robust configuration includes 40 digital inputs, 40 digital outputs, and 2 analog inputs, giving it the versatility needed for wide-ranging factory floor applications.
Designed for scalability, the FX5U-80MT/DSS supports up to 256 local I/O points and a total of 512 local + remote I/O points, accommodating system expansion without complexity. Its TRANSISTOR output type with SOURCE logic provides reliable, noise-resistant switching ideal for fast-acting control environments. Equipped with both an Ethernet port and RS-485 interface, it allows smooth integration with modern industrial networks and HMI/SCADA systems. An optional buffer battery enhances system resilience in power loss conditions.
The controller is built to endure with IP10 protection, an operating temperature tolerance up to 55Β°C, and compact dimensions of 285 mm width, 90 mm height, and 83 mm depth. At just 1.2 kg, it fits easily into standard control panels. Certified with CE, UL/cUL, and UKCA standards, and approved by marine authorities such as ABS, DNV GL, BV, and RINA, the FX5U-80MT/DSS is trusted globally for critical operations.
