Expert Review – Manager’s Insight

The M221 is a workhorse for small-scale automation. Its fast inputs (5 µs) handle precise counting, while the built-in PID saves external controllers. The Ethernet port simplifies integration with SCADA. For OEMs looking for a cost-effective, reliable controller, this is a top pick.

Typical Applications

• Packaging machines (capping, labelling)
• Conveyor systems (speed control)
• Small pumping stations
• HVAC damper control
• Test benches and data logging

FAQ – Frequent Questions

• Can I use this controller with a 24 V DC supply?

  No – it requires 100…240 V AC. Use a separate power supply for sensors.

• How many fast counters are available?

  Four inputs (I0, I1, I6, I7) support 100 kHz counting.

• Is the programming software free?

  Yes – SoMachine Basic is free and includes all features.

• Can I expand with digital I/O only?

  Yes – you can add up to 4 modules of mixed types.

• What is the relay life under heavy load?

  Mechanical durability >20 million cycles; electrical life varies with load (see table).

• Does it support remote access via internet?

  Yes – via Ethernet/IP or Modbus TCP with a VPN.

Selection Guide – Which M221 to Choose?

• TM221CE16R – relay outputs, 9 inputs, 2 analog (this model)
• TM221C16T – transistor outputs for fast switching
• TM221CE24R – more I/O if you need extra capacity
• For high-speed counting >100 kHz, consider the TM221C24T.
