PLC controller · 32 I/O 16 DI and 16 transistor DO Ethernet and serial Modicon M221 · Schneider Electric TM221ME32TK
Compact Modicon M221 PLC with 32 integrated I/O, including 16 digital inputs and 16 PNP transistor outputs, plus Ethernet, RS-232/RS-485, and USB connectivity. Commonly used for simple machine control and OEM panels where onboard I/O and network communication are needed.
What this product is for
This compact PLC is used for machine control, small automation cells, and OEM equipment that need onboard digital I/O with Ethernet and serial communications. It suits applications where panel space is limited but reliable control and integration are required.
Use for
- Simple industrial machines and skids
- Packaging, material handling, and utility control panels
- Applications needing 16 digital inputs and 16 transistor outputs
- Systems using Ethernet, RS-232, RS-485, or USB for programming and communication
- Expansion with compatible Modicon TM3 I/O modules where required
Avoid for
- Safety-rated control functions
- Applications needing relay outputs for direct switching of mixed voltage loads
- Large distributed control systems that require higher I/O counts or advanced network architectures
Best for
Best for electricians, panel builders, and OEMs needing a compact 24 VDC PLC with transistor outputs and built-in communications for straightforward machine automation.
Installed in
- Industrial control panels
- Machine cabinets
- Factory automation equipment
- Light commercial and industrial process skids
Why this product exists
The TM221ME32TK provides a compact control platform with integrated I/O and embedded communications, reducing the need for separate communication modules in smaller automation systems. This helps simplify panel layout, commissioning, and maintenance.
Compared with similar products
Compared with relay-output PLCs, this model uses PNP transistor outputs for faster switching and better suitability with DC control circuits. Compared with larger modular PLC platforms, it offers a smaller footprint at approximately 2.8 in W x 4.0 in H x 3.3 in D (70 x 102 x 85 mm), making it a practical choice for compact panels. Actual suitability depends on load type, control architecture, and local electrical code.
