The Mitsubishi FX3G-24MT/ESS is a 24/40-point programmable controller from the FX3G series, with 24 built-in I/O points expandable to 40 via extension units, transistor (drain) outputs for high-speed switching, and a DC24V power supply drawing 21W.
Key ratings and what they mean for fit
The basic unit 24/40 point. means the CPU carries 24 I/O points and can be expanded to 40 via extension units. Transistor (drain) outputs switch loads faster than relay types, rated for high-frequency actuation — fitting for solenoids, indicators, or direct stepper drive if the current stays within the module's specifications. DC24V supply matches the standard control voltage in most panels, so you can share a common 24V bus without a dedicated power supply. Power consumption of 21W is modest — a typical 24V 2A supply can power the controller with plenty of headroom for sensors and output loads.
