- Description
The Schneider Electric TM3DM8R is a Modicon TM3 mixed I/O module that adds 4 sink/source 24V DC inputs and 4 relay outputs (2 A) to a Modicon M221, M241, M251 or M262 logic controller. It wires through a removable screw terminal block with 5.08 mm pitch shared by inputs and outputs, and carries an IP20 rating.

Selection Notes
The TM3DM8R suits applications that need only a small mixed block - 4 inputs plus 4 relay outputs on a single 27.4 mm module - instead of the larger 16DI/8DO TM3DM24R. Its relay outputs switch small contactors or indicator loads directly from the module. Where the machine needs more than 4 inputs or 4 outputs, the TM3DM24R provides the higher-density 16DI/8DO option in the same product family.
