Frequently Asked Questions

Q: What is the safety level of the Pilz 751104?

A: In actual industrial safety system design, the specific safety level (Performance Level, PL or Safety Integrity Level, SIL) usually depends on the architecture of the entire safety loop (such as the combination of sensors, relays, and actuators). It is recommended that you consult the official complete instruction manual or technical manual accompanying this model to obtain the most accurate safety level certification data.

Q: What exactly does the forced guide contact of this relay refer to?

A: The "Force-guided contacts" in this relay are a special structural design that mechanically connects the normally open contacts (NO) and the normally closed contacts (NC) together. It does not mean that the relay "never fails", but rather ensures that it can take regular, safety-oriented actions when a failure occurs.

Q: What are the differences between its contacts and those of a regular relay?

A: Safety relays (such as the Pilz 751104) differ fundamentally from regular relays in their contact design. Regular relays primarily focus on the switching function of the circuit, while the contact design of safety relays is for "fail-safe" operation.
