Product Overview
When a compact and reliable logic controller is needed for small to medium automation tasks, the Schneider TM218LDA24DRN delivers. As part of the Modicon M218 series, this controller combines 24 discrete I/O points with a robust design suited for demanding industrial environments. With 14 voltage inputs and 10 relay outputs, it handles sensor and actuator control efficiently.
Technical Specifications Breakdown
The TM218LDA24DRN operates on a rated supply voltage of 100...240 V AC, with supply voltage limits of 85…264 V. Power consumption is 25 W at nominal voltage, and the power supply input current is 250 mA at 22...27 V. The 14 discrete inputs accept 24 V DC, with input impedance of 4700 Ohm for standard inputs and 2800 Ohm for high-speed inputs. Response time is 2 ms for both turn-on and turn-off. The 10 relay outputs have output voltage limits of 19.2...28.8 V DC, with a maximum voltage drop of less than 1.5 V. The controller supports shielded cable distances up to 5 m. Environmental resilience includes an IP20 degree of protection, shock resistance of 15 gn for 11 ms, vibration resistance of 3.5 mm at 5…150 Hz, and an operating temperature range of 0…55 °C. Storage temperature ranges from -25…70 °C, with relative humidity up to 95% without condensation. Pollution degree is 2, and operating altitude is 0...2000 m.
Industry Applications
From a maintenance engineer's perspective, the TM218LDA24DRN excels in packaging lines, conveyor control, and small machine automation. Its 14 inputs connect to limit switches and proximity sensors, while the 10 relay outputs drive contactors and indicators. The 2 ms response time ensures precise timing for sorting or labeling tasks. The wide supply voltage range and IP20 enclosure make it suitable for control cabinets in light manufacturing.
Installation & Setup Guidance
Mount the TM218LDA24DRN on a DIN rail inside an enclosure. Ensure the supply voltage is within 85…264 V AC before connecting. Use shielded cable for distances up to 5 m to maintain signal integrity. Wire inputs to 24 V DC sources and outputs to relay loads within 19.2...28.8 V DC. Verify that the ambient temperature stays between 0…55 °C and that relative humidity remains below 95% without condensation.
Maintenance & Reliability
For reliable operation, inspect the controller periodically for dust accumulation and ensure ventilation openings remain clear. Check all wiring connections annually for tightness. The TM218LDA24DRN's solid-state design minimizes wear, but relay outputs should be tested regularly for contact degradation. Operating within the specified temperature and humidity ranges extends service life. SpareTechPLC recommends verifying the current lifecycle status before ordering, as availability may vary.
Selection Guide & Purchasing Advice
Before purchasing the TM218LDA24DRN, confirm that your application requires 14 inputs and 10 relay outputs. Verify that the supply voltage matches your facility's power (100...240 V AC). The controller weighs 716.0 g and measures 18.2 cm x 9.5 cm x 12.8 cm, so ensure adequate cabinet space. SpareTechPLC offers this logic controller with CE certification and reliable support for your automation needs.
