Frequently Asked Questions
PLC Transistor and Relay Precautions
The PLC output is common cathode with theoretical rating of 1A (actual use under 500mA). COM wiring is negative, use 24V voltage. No voltage output when used as switch. External relays require external power supply.
Relay contact life: theoretical 300,000 cycles. External load should not exceed 5A. Frequent full load operation may affect service life.
Output Type Selection Guide
MT: Transistor output
MR: Relay output
MRT: Relay-transistor mixed output
MR: Relay output
MRT: Relay-transistor mixed output
Key Differences:
- Current Load: Transistor max 500mA, Relay max 5A
- Output Power: Transistor - DC24V only, Relay - DC24V or AC220V
- Functionality: Use transistor output for pulse driving (stepper motors) or active output switching
- Recommendation: When both options are available, transistor output is preferred due to no contact life limitations and longer operational lifespan when current limits are observed
