That means it lands on a standard machine control transformer or direct line feed without a separate DC power supply module. Inrush current hits 30 A at 110 Vac and 60 A at 240 Vac — the internal bulk caps charge hard on power-up. Size the upstream circuit breaker or fuse to ride through this pulse without nuisance tripping; a C-curve MCB or slow-blow fuse handles it cleanly. The controller tolerates a 10 ms power dip at 100 Vac before the logic resets — enough to ride through a contactor dropout or brief line sag without a UPS in most industrial environments. Continuous output power draw is 34 W — the internal 24 VDC supply for the IO bus and sensor power is already accounted for in that figure. No external 24 V supply needed for the base unit. ## IO complement — 24 inputs, 16 relay outputs, plus analog Twenty regular digital inputs plus four fast inputs (for high-speed counters) give you 24 sinking inputs total at 24 VDC. The four fast channels handle encoder or pulse-train inputs up to the HSC rate without missing edges. Sixteen relay outputs on the base unit — rated for switching AC and DC loads up to the contact ratings. Relay outputs are forgiving for mixed-voltage field wiring; no polarity concerns, and they isolate the load from the logic side. Two analog outputs are built in — no separate analog module needed for simple setpoint or speed-reference signals. Handy for driving a small VFD or valve positioner straight from the base unit. Expansion capacity goes to 248 total I/O points with up to 7 expansion modules and a maximum of 90 relay outputs across the system. That covers a medium-sized machine or small line without swapping to a larger controller family. ## Isolation and compliance — what the 1780 Vac rating means Isolation between the AC power supply and the internal logic, IO, and protective earth is rated at 1780 Vac / 2500 Vdc. That's a reinforced insulation level — the controller can be wired directly to line voltage on the same panel as sensitive analog circuits without galvanic coupling issues.","metaTitle":"Schneider TM218LDA40DR2HN Modicon M218 PLC, 100-240 Vac","metaDescription":"Schneider Electric TM218LDA40DR2HN Modicon M218 logic controller, 100-240 Vac supply, 24 digital inputs, 16 relay outputs, 2 analog outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Rated":"100...240 Vac","title":"TM218LDA40DR2HN","Voltage":"Rated : 100...240 VacLimit (including ripple) : 85...264 Vac","Frequency":"50/60 Hz","At 110 Vac":"30 A","At 240 Vac":"60 A","Product No.":"TM218LDA40DR2HN","description":"Modicon M218 Logic Controller","Analog Input":"No","Product Type":"Modicon M218 Logic Controller","Analog Output":"2 analog outputs","Digital Input":"20 regular inputs and 4 fast inputs (HSC)","Digital Output":"16 relay outputs","Shipping Weight":"2 Kg","lifecycle_stage":"current","Estimated Lead Time":"1 - 10 working days.","Maximum inrush current":"At 110 Vac : 30 AAt 240 Vac : 60 A","Continuous output power":"34 W","Power interruption time":"10 ms at 100 Vac","Limit (including ripple)":"85...264 Vac","Maximum Number of I/O Points":"248","Maximum Number of Relay Outputs":"90","Maximum Number of Expansion Modules":"7","Isolation between AC power supply and internal logic, I/O and protective ground (PE)":"1780 Vac/2500 Vdc"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$298.00 – $677.23","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/247b7c1249a9544deb6a8da98a28e852.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many inputs and outputs does this controller have on the base unit?","answer":"The base unit has 24 digital inputs (20 regular plus 4 fast inputs for HSC), 16 relay outputs, and 2 analog outputs.
