The Schneider TM218LDA40DRN is a Modicon M218 logic controller with 40 I/O points: 22 digital inputs that accept sink or source wiring over 0…28.8 VDC, and 16 relay outputs for switching loads up to the relay's rating.
Input specifics and wiring flexibility
The 22 inputs are configurable as sink or source, so both PNP and NPN sensors connect without pull-up/down resistors. Each input draws either 7 mA (enhanced mode) or 5 mA (standard mode), both within the 0...28.8 VDC range. There is no overvoltage protection on the inputs. In environments with inductive switching or long cable runs, an external surge suppressor on each input line is worth budgeting for.
We quote this part against an RFQ with confirmed lead time and pricing. No known cross-reference or alternate MPN exists in the same family — the TM218LDA40DRN is the specific variant for 22 inputs and relay outputs.
