Schneider's TM218LDA60DRN is a current-production Modicon M218 logic controller. It accepts sink or source inputs from 0…28.8 Vdc, with configurable input draw: 7 mA enhanced, 5 mA standard.
Input wiring and power budget
The sink/source input type allows NPN or PNP sensors without a separate module. At 7 mA enhanced draw, noise immunity improves; switch to 5 mA to reduce power. Input range is 0…28.8 Vdc — no overvoltage protection, so use a regulated supply within that range.
