Product details

Overview

The TM221ME16T is a Modicon M221 logic controller from Schneider, packing 16 discrete I/O — 8 inputs (4 fast) and 8 transistor outputs rated at 0.5 A each — into a 71.12 mm square footprint. It runs on 24 V DC and carries 256 kB memory for user application and data, programmable via SoMachine Basic.

Compared to the TM221ME32TK, the TM221ME16T halves the I/O count (16 vs 32) and lacks the extra 256 kB data memory of the larger sibling, making it the right fit for smaller standalone machines where 16 points and the base memory suffice. The TM221ME16R variant swaps transistor outputs for relay outputs (2 A max), so choose the T version when driving DC loads like solenoid valves or LED indicators directly without an interposing relay.

The TM221ME16T is an active catalogue item; no obsolescence notice is recorded. It carries CE marking and complies with IEC 61131-2, UL 508, CAN/CSA C22.2 No. 213, IACS, and ANSI/ISA 12-12-01, plus California Proposition 65 — documentation for panel certification is available on request.

Integration notes

Mounts on TH35-15 or TH35-7.5 DIN rail per IEC 60715, or on a plate with the fixing kit. The serial link supply is 5 V at under 200 mA — budget that separately if powering an external Modbus device from the port. Shock rated at 147 m/s² for 11 ms; the controller survives moderate machine vibration without additional dampening.
