Detailed Answer
PLC integration: 1. Output mode: relay dry contact (directly into PLC input) or RS485/CAN bus (data exchange); 2. Interlock: PLC interlock signal wired into the receiver; 3. Monitoring: operation logs/status uploaded to PLC. Selection key points: confirm PLC brand/protocol (Modbus etc.), I/O points, interlock requirements. LDER LD series: relay + RS485; XINGJIA: CAN optional.
| Output | Relay / bus |
| Interlock | Signal input |
| LDER | RS485 |
Note:Confirm PLC interface requirements early to avoid retrofits.
