FAQ – Experience & Selection Guide

• Q: Does TM221CE24R support high-speed counting?
  A: Yes. It has 4 fast inputs (HSC) up to 100 kHz, 32-bit counter. Use I0, I1, I6, I7 for fast response.
• Q: Can I expand I/O beyond the built-in 24 points?
  A: Yes. Connect up to 7 expansion modules (relay or transistor) via the bus.
• Q: What software do I need for programming?
  A: Use SoMachine or EcoStruxure Machine Expert – both support M221 series.
• Q: Is the relay output suitable for inductive loads?
  A: Yes. Electrical durability for AC-14/DC-13 is rated up to 300k cycles. Use external protection for high current.
• Q: How to choose between relay and transistor output?
  A: Relay outputs (like this model) handle AC/DC and high voltage; transistor outputs are faster but DC only. Select based on load type.
• Q: What is the backup battery life?
  A: BR2032 lithium battery provides 4 years typical, with 1 year data retention at 25°C after power loss.
• Q: Does it work in marine environments?
  A: Yes. Certified by DNV-GL, LR, and meets marine conducted immunity specs.
