Schneider Electric TM221M32TK Modicon M221 Book 32 I/O Transistor Logic Controller

The Schneider Electric TM221M32TK 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 in a 70 x 70 x 90 mm housing. Supplied from 24 V DC, each output switches 0.1 A (1.6 A per common), suited to dense low-current point counts.

Selection Notes

The TM221M32TK doubles the Book controller's I/O count to 32 points through HE-10 connectors instead of the 16-point models' screw terminals, which suits panel builders using pre-wired ribbon-cable harnesses. Its lower 0.1 A per-channel and 1.6 A per-common output rating reflects the higher channel density — it fits many low-current 24 V DC loads (PLC inputs, small relays) rather than a handful of higher-draw actuators.
