Product details

TM221ME16TG is a Modicon M221 brick-style PLC with 16 discrete I/O. Transistor outputs are sink or source, and fast inputs (I0, I1, I6, I7) switch in 5 µs — enough for incremental encoder capture and pulse counting. Ethernet port runs 10BASE-T/100BASE-TX for Modbus TCP, so no extra communication card needed for networked control. The controller supports up to 14 independent PID loops, enough for small process skids or temperature zones. Real-time clock with a lithium coin cell (BR2032 or CR2032X) maintains time and RAM backup for one year at 25 °C — no ongoing battery replacement schedule if the panel stays powered. Insulation is 500 V AC between input/logic and output/logic; inputs and analog channels are non-isolated from each other. Use isolated signal conditioners on shared analog fields to avoid ground loops.

Agency marks include CE, UL 508, CSA C22.2 No. 213, and IEC 61131-2, so it clears most panel certifications in North America and Europe without separate testing.

The 70 mm x 90 mm face saves rail space; allow clearance for the RJ45 and USB connectors on the front. Discrete inputs accept sink or source wiring; common negative or positive. Transistor outputs are protected against short circuits (1 A threshold) with automatic reset — no fuses needed per channel for typical load wiring.
