This controller provides a balanced mix of inputs and outputs for general-purpose control. The TM218LDA40DRN belongs to the Modicon M218 series, offering 40 discrete I/O points in a compact base unit. Its design focuses on reliability and ease of use for standard automation applications.
The TM218LDA40DRN includes 24 voltage inputs for connecting various sensors and switches. The discrete input voltage is rated at 24 V DC, which matches most standard industrial sensors. Input impedance measures 4700 Ohm for standard inputs, ensuring proper signal detection. For high-speed applications, the fast inputs present 2800 Ohm impedance. The response time reaches 2 ms for both turn-on and turn-off transitions. This fast response suits applications requiring quick signal detection. The input voltage type is DC, supporting sink or source wiring configurations.
This model provides 16 relay outputs for switching external loads. Relay outputs offer versatility for AC or DC load switching. The maximum voltage drop across each output stays below 1.5 V for efficient operation. The output voltage limits range from 19.2 to 28.8 V DC. Additionally, the output type supports various load types including inductive and resistive loads. For inductive loads, we recommend using external snubber circuits to protect the relay contacts. This extends the lifespan of the TM218LDA40DRN outputs.
The rated supply voltage is 100 to 240 V AC, covering most global power standards. Supply voltage limits extend from 85 to 264 V AC, accommodating voltage fluctuations. The power consumption reaches 34 W at 100 to 240 V AC. Power supply input current is 300 mA at 22 to 27 V for internal logic. The maximum cable distance between devices is 5 meters when using shielded cable. Therefore, you should place remote I/O devices within this distance.
The analog input number is specified as 24, indicating versatile analog capability. However, please verify the exact analog configuration based on your specific model variant. The TM218LDA40DRN offers a comprehensive I/O mix for mixed-signal applications. Its compact design saves valuable panel space in control cabinets.
The IP degree of protection is IP20, suitable for installation in protected enclosures. The operating temperature ranges from 0 to 55 °C for reliable performance. Storage temperature extends from -25 to 70 °C for flexible warehousing. Relative humidity tolerance reaches 95% without condensation, accommodating humid environments. Vibration resistance is 3.5 mm at 5 to 150 Hz, ensuring durability in industrial settings. Shock resistance measures 15 gn for 11 ms, handling mechanical impacts during operation. The pollution degree is rated at 2, indicating suitable for non-conductive contamination. Operating altitude extends to 2000 meters, while storage altitude reaches 3000 meters. Product certifications include CE, confirming compliance with European standards.
First, mount the TM218LDA40DRN onto a standard 35 mm DIN rail. Ensure the enclosure meets IP20 requirements for protection. Next, connect the AC power supply to the designated terminals within the rated voltage range. For inputs, wire your 24 V DC sensors in sink or source configuration. Meanwhile, connect output loads to the relay terminals with proper protection. Additionally, use shielded cables for connections exceeding short distances. Keep cable runs under 5 meters for reliable signal transmission. Finally, verify all wiring connections before applying power to the system.
This controller suits a wide range of small to medium automation applications. For example, you can use it for conveyor control, packaging machinery, or simple assembly stations. The TM218LDA40DRN also works well in HVAC systems and building automation. Furthermore, it fits OEM equipment requiring reliable discrete I/O control. Its CE certification ensures acceptance in European markets.
