The TM218LDD24DUPHN is a compact logic controller from the Schneider Electric Modicon M218 range. This unit packs 24 built-in I/O points into a slim housing. Specifically, it provides 14 digital inputs and 10 transistor outputs. Moreover, it includes two high-speed counters at 10 kHz and two pulse outputs up to 100 kHz. The controller runs on a 24 V DC supply and draws about 15 W. Additionally, two RS-485 ports support Modbus RTU and ASCII protocols. A mini USB-B port handles programming duties. Engineers use it for packaging, small assembly, and material handling machines. The TM218LDD24DUPHN works with SoMachine and EcoStruxure Machine Expert software. Furthermore, it accepts up to seven TM2 expansion modules for 248 total I/O.
The TM218LDD24DUPHN carries 1 MB Flash memory for program and data backup. It also provides 1 MB RAM for application execution. Scan speed reaches 1 Kinst per 2 ms under typical mixed loads. Furthermore, the digital inputs split into 10 regular 24 Vdc points and 4 fast HSC inputs at 10 kHz. The 10 transistor outputs use source (PNP) wiring and handle 0.5 A per point. Besides, two of those outputs serve as fast PTO or PWM channels reaching 100 kHz. However, the unit offers no analog inputs or outputs.
Two RS-485 terminal block ports support Modbus RTU and ASCII. Meanwhile, a mini USB-B port carries the proprietary programming protocol. In addition, a communication cartridge slot accepts TMCOM series modules. These add optional Modbus, CANopen, or Profibus connectivity. Therefore, the controller adapts to different network requirements.
Supply voltage ranges from 19.2 to 28.8 V DC, with 24 V DC nominal. Power consumption sits near 15 W, and the unit needs no backplane bus. Operating temperature spans 0 to +55 °C. Storage temperature covers -25 to +70 °C. Relative humidity runs from 10 to 95% without condensation. The protection rating is IP20, so it belongs inside a clean cabinet. Moreover, the housing measures 94.5 mm high, 87.5 mm wide, and 70 mm deep. Its weight reaches roughly 0.35 kg.
Installation follows simple panel-mount steps. First, fix the controller to a DIN rail or mounting plate. Next, wire the 24 V DC supply to the dedicated terminals. After that, connect inputs, outputs, and RS-485 lines with shielded cable. Then attach the USB cable for programming. Finally, verify all terminal torques before power-up. However, always separate signal wiring from high-voltage cables to reduce noise.
Schneider Electric has discontinued this model. The recommended replacement is the Modicon M221 range. Furthermore, new projects should consider M241 or M258 controllers. Nevertheless, the TM218LDD24DUPHN remains available for existing installations and spare-part demand.
