Schneider Electric TM221ME32TK Modicon M221 Book 32 I/O Transistor Ethernet Logic Controller

The Schneider Electric TM221ME32TK is a Modicon M221 Book-format logic controller with 32 discrete I/O — 16 inputs (4 fast) and 16 PNP transistor outputs (2 fast) — wired through HE-10 connectors, plus a built-in Ethernet RJ45 port for Modbus TCP and EtherNet/IP. Supplied from 24 V DC, each output switches 0.1 A (1.6 A per common).

Selection Notes

The TM221ME32TK pairs the 32-point HE-10 transistor Book controller with built-in Ethernet, so choose it over the serial-only 32 I/O variant when dense-channel machines also need Modbus TCP or EtherNet/IP reporting. Each output's 0.1 A rating (1.6 A per common) still fits the same low-current 24 V DC loads the non-Ethernet model targets. The DHCP client lets it pick up an IP address automatically on commissioning, which simplifies swapping a controller in the field without a static-address reconfiguration step.
