This controller offers a cost-effective solution for managing small-scale machinery. The TM218LDA24DRN is part of the Modicon M218 series, specifically designed for simple yet precise control applications. Its compact footprint makes it ideal for panels with limited space.
This model has 12 regular digital inputs and 2 fast inputs for high-speed counting (HSC). The digital outputs consist of 10 relay outputs for switching various loads. For standard operation, the input current is 5 mA. In enhanced mode, the current increases to 7 mA. The TM218LDA24DRN supports both sink and source wiring, offering great installation flexibility. It operates within a wide input voltage range from 0 to 28.8 Vdc. However, please note that this unit has no built-in protection against over voltage. You should incorporate external protection devices for stable operation. Furthermore, its logic processing capability is well-suited for managing conveyor belts, packaging tools, and basic positioning tasks.
This controller operates reliably in a standard industrial environment. Its operating temperature range is from 0°C to 55°C. The relative humidity for operation should be between 10% and 90% without condensation. It is designed to withstand vibration and shock according to IEC standards. For storage, the temperature can be from -25°C to 70°C. The unit uses a removable screw terminal block for easy wiring. Moreover, the compact dimensions allow for direct mounting on a DIN rail in your control cabinet.
First, mount the TM218LDA24DRN securely onto a standard 35 mm DIN rail. Ensure proper grounding to protect against electrical interference. Next, connect the power supply to the dedicated terminals, observing the polarity. For the inputs, connect your sensors based on the sink or source configuration. Additionally, the relay outputs can switch inductive loads, but you should use snubbers for protection. Meanwhile, verify that the voltage for all I/O points remains within the specified range to avoid damage. Finally, check all connections before powering up the system.

What is the difference between fast and regular inputs?
The two fast inputs support high-speed counting (HSC) up to a certain frequency. This makes them ideal for reading signals from speed sensors or encoders. The other 12 inputs are standard for general-purpose discrete signals.
Can I use both sink and source wiring on this model?
Yes, the TM218LDA24DRN provides full flexibility for both sink and source wiring. This allows you to connect various types of PNP or NPN sensors. Consequently, you have more options during system design.
What should I do if the unit lacks over-voltage protection?
We highly recommend installing a surge suppressor or a fuse on the power supply line. This precaution will safeguard the TM218LDA24DRN from unexpected voltage spikes. It also ensures the longevity of your entire control system.
How do I wire the relay outputs?
The relay outputs are normally open contacts. You can wire them to switch AC or DC loads. However, always ensure the load current remains within the relay's rated capacity.
What software is needed to program this controller?
You need Schneider Electric's EcoStruxure Machine Expert - Basic software. This is the dedicated programming environment for the Modicon M218 series. It offers a user-friendly interface for creating your logic programs.
