Frequently Asked Questions
PLC Transistor and Relay Usage Precautions
- PLC output is common cathode with theoretical 1A rating (actual use < 500mA)
- COM wiring is negative - use 24V voltage with no voltage output when used as switch
- External relays require separate power supply
- Relay contact life: theoretical 300,000 cycles
- External load should not exceed 5A theoretical value
- Frequent full load current may reduce service life
Output Type Selection Guidelines
- MT: Transistor output
- MR: Relay output
- MRT: Relay-transistor mixed output
Transistor vs. Relay Output Comparison:
- Current Load: Transistor: 500mA max; Relay: 5A max (3A for EX2N(S)/DX2N(S) series)
- Output Power: Transistor: DC24V only; Relay: DC24V or AC220V
- Applications: Use transistor output for pulse-driven applications (stepper motors) or active output switches
- Recommendation: When both options are available, transistor output is preferred due to no contact life limitations and longer service life when current limits are observed
