I/O Density and Signal Processing

The TM218LDA40DR4PHN combines discrete and analog signal interfaces in a compact M218 controller architecture. Its listed 40 discrete I/O points include 24 DC voltage inputs, 12 relay outputs, and 4 transistor outputs. The controller also specifies 24 analog inputs with 0-20 mA and 4-20 mA current ranges, together with analog voltage and current outputs.

The 2 ms turn-on and turn-off response specification applies to the listed discrete input response. Input impedance differs between standard and high-speed inputs, at 4700 Ohm and 2800 Ohm respectively. Shielded device cabling is specified at less than 5 m between devices.

The controller accepts 100 to 240 VAC nominal supply voltage with an operating limit of 85 to 264 V. Its specified power consumption is 34 W at 100 to 240 VAC.

Field Installation Guidelines

• Install the controller in an enclosure consistent with its IP20 protection rating.
• Maintain wiring separation between power conductors and low-level analog signal conductors to reduce electrical interference.
• Use shielded cable where the installation requires it; the supplied specification limits shielded device cable distance to less than 5 m.
• Connect 24 VDC discrete signals according to the input circuit requirements and observe the specified input impedance.
• Separate relay-output wiring from analog signal wiring where practical to reduce coupling.
• Verify the supply remains within the specified 85 to 264 V input range before energizing the controller.
• Provide appropriate protective grounding and cabinet bonding in accordance with the installation site's electrical standards.
• Observe the 0 to 55 deg C operating ambient range and avoid installation locations exceeding the specified humidity and pollution conditions.
• The TM218LDA40DR4PHN is listed as discontinued on 16 Apr 2024, with end-of-service scheduled for 15 Jan 2030. Schneider Electric lists Modicon M221, Modicon Easy M100, and Modicon Easy M200 product ranges as replacement options.
