Modicon M221 Nano PLC
The smallest Modicon controller: an all-in-one block with embedded I/O for simple sequences, interlocking and local control. It is the right answer for a retrofit where relay logic is replaced by a programmable controller without redesigning the entire cabinet.
Key characteristics
- Embedded 16 to 40 digital I/O, relay or transistor outputs
- Optional analog inputs and TM3 expansion
- Ethernet or serial models, USB programming port
- Fast counters and pulse outputs for basic positioning
- Engineering in EcoStruxure Machine Expert – Basic (free)
Typical applications
Small machines, local pump and fan control, retrofit panels
