TM258LF66DT4L Modicon M258 Logic Controller 24 VDC Transistor

TM258LF66DT4L Schneider Electric Modicon M258 Compact Logic Controller

The TM258LF66DT4L is a compact logic controller from the Schneider Electric Modicon M258 series. It packs 66 I/O points and 4 analog inputs into one rugged unit. A dual-core ARM Cortex-A8 processor separates program tasks from communication tasks. This design keeps scan cycles fast and stable. The controller runs on 24 VDC and uses transistor outputs. It suits machine control, motion tasks, and distributed automation. Built-in Ethernet, CANopen, and RS-485 ports cut wiring work. Up to 7 TM5/TM2 expansion modules scale the system to 2400 I/O. Two free PCI slots add communication or function modules. The IP20 housing measures 99 × 265 × 75 mm and weighs 0.8 kg. This unit remains Active in the Schneider lifecycle.
