The Schneider Electric TM3TM3 is a Modicon TM3 expansion module that combines 2 analog or temperature inputs (current, voltage, thermocouple or RTD, 16-bit) with 1 analog current/voltage output, adding mixed I/O to Modicon M221, M241, M251 and M262 logic controllers on a 24 V DC supply. Output resolution matches the inputs at 16-bit, with 0.1% full-scale accuracy on both channels at 25 degrees C.
The TM3TM3 combines input and output channels on a single module, useful when a panel needs both a sensor reading and a control signal, for example a VFD speed reference, without using two separate TM3 slots. Pick a dedicated input-only or output-only TM3 module instead when the application only needs one signal direction.
