TM221CE16R: Modicon M221 Logic Controller with 16 I/O, Relay Outputs and Ethernet

The TM221CE16R comes from the Modicon M221 range built by Schneider Electric. This logic controller runs on 100 to 240 V AC supply. It packs 16 discrete I/O, including 9 inputs and 7 relay outputs. Two analog inputs handle 0 to 10 V signals with 10-bit resolution. An RJ45 Ethernet port adds Modbus TCP and Ethernet/IP support. Engineers pick this model for small machines, building automation and compact process control.
