It is neither. The "M" stands for . It exists only inside the PLC’s memory. You cannot wire a physical switch to it, and it cannot drive a real load directly. You must use its contact to trigger an output coil (Y0, Y1, etc.). M8013 vs. Other Special Relays | Relay | Pulse Rate | Common Use | | :--- | :--- | :--- | | M8011 | 10ms (100 Hz) | High-speed flashing, test pulses | | M8012 | 100ms (10 Hz) | Fast blinking, short delays | | M8013 | 1 second (0.5 Hz) | Human-scale timing, indicators | | M8014 | 1 minute (0.0167 Hz) | Long-interval polling, hour meters | Final Verdict: Should You Use M8013? Absolutely. M8013 is one of those elegant, simple tools that makes PLC programming faster and more readable. Instead of writing a 5-rung timer oscillator, you write one contact. m8013 mitsubishi plc
