The FX3SA-20MT-CM: The transistor outputs are sink-type (drain), suitable for switching DC loads up to the rated current. This allows faster switching than relay outputs and longer life in high cycle applications. Built-in USB and RS-422 communication ports simplify programming and connection to HMIs or drives. The high-speed counter inputs support 1-phase 60 kHz on 2 points and 10 kHz on 4 points for encoder feedback. Power consumption is 20W, making it efficient for small control panels. The compact 20-point package fits tight spaces.

Frequently asked questions
What is the output type of the FX3SA-20MT-CM?
The outputs are transistor (drain/sink) type, not relay. This makes it suitable for high-speed DC loads.
Can the FX3SA-20MT-CM replace a LJ71C24-R2-CM in a panel?
No. The LJ71C24-R2-CM is a communication module, not a PLC. The FX3SA-20MT-CM is a programmable controller with integrated I/O. They have different form factors and functions, so they are not drop-in replacements.
