FX3U-80MT/DSS MITSUBISHI MELSEC FX3U 80 I/O 24V DC Transistor PLC Base Unit
The FX3U-80MT/DSS MITSUBISHI (Model: FX3U-80MT/DSS) is a compact programmable logic controller main unit from the Mitsubishi Electric MELSEC FX3U Series. Designed for 24V DC power environments, the FX3U-80MT/DSS MITSUBISHI features 40 digital inputs and 40 source-type (PNP) transistor outputs, offering high-density control capacity for mobile equipment, battery-backed panels, and low-voltage industrial systems.
Powered by a 24V DC supply, the FX3U-80MT/DSS MITSUBISHI operates at processing speeds as fast as 0.065 microseconds per basic instruction. It includes built-in high-speed counter inputs (up to 100 kHz) and high-speed pulse outputs (up to 100 kHz across 3 axes), making it ideal for multi-axis servo positioning and automated machinery operating on DC control buses.
Key Features of the FX3U-80MT/DSS MITSUBISHI
-
24V DC Main Power Operation: Designed specifically for systems powered by direct 24V DC bus installations or marine DC supply rails.
-
High-Density Onboard I/O: Integrates 40 24V DC inputs and 40 source transistor (DSS / PNP) outputs in a single housing.
