Product details

Compact PLC with 16-point I/O – what fits where

The TM221CE16R is a current-production Modicon M221 controller packing 16 discrete I/O into a 95 mm wide × 90 mm tall × 70 mm deep housing. That dimension – 95 mm wide – is the one that matters when you're booking DIN rail space alongside terminals and a power supply. It's sized for top-hat rail (TH35-15 or TH35-7.5) or direct plate mounting, so no surprises on the panel layout.

Signal path constraints worth knowing

Discrete inputs sit at 3.4 kΩ – that's on the lower side, so check voltage drop across long cable runs or marginal NPN sensors. Fast inputs (I0, I1, I6, I7) respond in 5 µs turn-on / 35 µs turn-off, enough for single-phase pulse counting up to maybe 20 kHz depending on duty cycle; the slower inputs are 35 µs / 100 µs. Analog conversion runs 1 ms per channel plus one scan cycle – not for high-speed PID but fine for temperature or pressure trends. The built-in PID handles up to 14 loops, so you can close a few process loops without an extra module.

Compliance and standards – what's on the nameplate

This unit carries CE marking and holds UL 508, CSA C22.2 No. 213, IEC 61131-2, and ANSI/ISA 12-12-01 (Class I Div 2) approvals. The surge immunity numbers are detailed: 2 kV common mode on AC power lines, 1 kV on I/O shielded cables. If your panel must pass a UL 508A listing, the TM221CE16R covers that base. Production status is current – still in active manufacture, no end-of-life notice.
