Interface Relay Module - 1CO, 6A/250Vac 30Vdc, 12Vdc coil, 12V AC/DC input, (SNC05-S-A) is a DIN rail interface relay module designed for industrial control and automation switching. Socket-conditioned input allows AC or DC supply while maintaining a DC relay coil where specified.
🔧 Technical Highlights:
- Contact configuration: 1CO (SPCO)
- Contact rating: 6A/250Vac 30Vdc
- Relay coil voltage: 12Vdc
- Pick-up voltage (12Vdc coil): 9Vdc (can be driven from 0-10V PLC outputs)
- Socket supply voltage: 12V AC/DC
- Socket type: SNC05-S-A
- Supply note: Socket input accepts AC or DC at the rated supply voltage.
- Available RNC coil options: 5Vdc, 6Vdc, 12Vdc, 24Vdc, 48Vdc, 60Vdc
✅ Benefits:
- Clear separation of socket supply voltage and relay coil voltage.
- Socket supply can be AC or DC for flexible control power wiring.
- Ultra-slim interface format supports high-density I/O marshalling.
- Interposing relay output for PLC and automation signals.
- 9V pick-up supports switching from 0-10V PLC outputs where applicable.
🚀 Applications:
- PLC output interfacing and signal isolation.
- Automation control panels and marshalling cabinets.
- Switching pilot loads and control signals.
Specified coil and contact ratings support correct selection and reliable panel operation.
FAQs
- Q: Can the 12Vdc coil be driven from a 0-10V PLC output?
A: Yes. The 12Vdc RNC coil has a 9V pick-up threshold, so it can be switched by a 0-10V output when the control circuit is designed for it.
- Q: Is the module supply AC or DC?
A: The SNC05-S-A socket is designed for 12-24V AC/DC and can be powered from AC or DC. The socket circuitry provides the correct drive for the relay coil.
