The Schneider Electric TM5C24D18T is a 24V DC high-capacity Power Supply Module for the Modicon TM5 modular I/O system (part of the MachineStruxure™ architecture). It converts an external 24V DC supply into a clean, isolated, and regulated 24V DC power source to energize the TM5 backplane bus, all connected I/O modules, and associated field devices within a control cabinet or remote station.
