Schneider TM221CE16T – compact Modicon M221 PLC (logic controller, Modicon M221, 16 IO, 9 DI, 7 DO, transistor, PNP, Ethernet).
If a machine stops because the PLC has failed, the fastest fix is an identical controller with the program reloaded from the backup; that is why many plants keep one spare M221 of each type in stock.

Key characteristics (per Schneider)
- logic controller
- Modicon M221
- 16 IO
- 9 DI
- 7 DO

Typical applications
- Replacement of a failed M221/M241 controller
- Packaging, pumping and conveying machines
- Machine retrofits from older Twido controllers
- Small process skids and water stations
Compatibility and replacement
Twido controllers (TWD) are discontinued; the M221 is the usual Schneider migration path. Send us the old reference and I/O count and we will suggest the matching model.
Frequently asked questions
Does it have Ethernet?
Yes, CE versions have an integrated Ethernet port (Modbus TCP and programming).
Relay or transistor outputs?
Relay outputs (R) switch AC or DC loads up to the relay rating; transistor outputs (T) are for fast 24 V DC loads and pulse outputs.
Which software do I need?
EcoStruxure Machine Expert – Basic for M221 (free), EcoStruxure Machine Expert for M241.
Can I copy the program from the old controller?
Yes, if the old controller still works and is not protected, the application can be uploaded and downloaded to the new unit with the Schneider software.
How fast can you deliver, and is there a warranty?
Air shipping usually takes 5 to 7 days once the part is ready, to almost any country. Each part is new and original with a 1-year warranty. Message us on WhatsApp with the order number for a quotation.
Before you order
Compare the complete order number on the old unit with this page, including the suffix: in most ranges the last characters set the coil voltage, current range or version. If the label is worn, send us a photo and we will identify the part.
