A：
To ensure that the safety door lock is compatible with the safety control system, you need to start from the following key aspects:
✅ 1. Electrical interface matching
Confirm that the operating voltage of the door lock (such as 24V DC) is consistent with the control system.
Check whether the output/input signal type (PNP/NPN, normally open/normally closed, etc.) is compatible.
✅ 2. Communication protocol consistency
If the door lock uses bus communication (such as IO-Link, PROFIsafe, AS-i Safety, etc.), you need to ensure that the control system supports the corresponding protocol.
✅ 3. Safety level matching
Determine the required safety integrity level (SIL) or performance level (PL) according to the application scenario.
Ensure that both the door lock and the control system meet the corresponding level (such as SIL2/PL d, SIL3/PL e).
✅ 4. Certification and standard compliance
Check whether the product has passed international safety standard certification (such as ISO 13849, IEC 62061).
Products certified by the same system are more compatible with each other.
✅ 5. Functional testing and compatibility verification
Actually access the control system and conduct functional tests such as switch linkage, fault response, and reset logic.
If necessary, contact the original manufacturer's technical support for compatibility confirmation.
If further customization or confirmation of the compatibility of the product combination is required, it is recommended to provide the current control system model, and we can assist in comparing the compatible door lock model.
