Pilz 774306 PNOZ X2.1 24VAC/DC 2n/o PNOZ series stand-alone safety relays

Core Features

• ✓  Dual-channel detection module: As the core safety control unit, it monitors two safety input signals in real time. If either channel disconnects, the output is immediately cut off to ensure safety.
• ✓  Forced-guided contact assembly: Utilizing a patented forced-guided structure, it ensures reliable disconnection even if contacts fuse, physically eliminating potential safety hazards.
• ✓  Short-circuit detection unit: Built-in cross-contact short-circuit detection circuit monitors contact status in real time and immediately triggers protection upon the occurrence of a short-circuit fault.
• ✓  Reset control mode: Supports switching between automatic and manual reset modes. Manual reset requires manual confirmation, further enhancing operational safety.
• ✓  Installation and connection: Adapts to industry-standard 35mm DIN rails, supporting installation at any angle; uses screw-type fixing terminals for secure wiring and stable contact.

Q: What are the main application scenarios for this relay?

A: This product is mainly used in the basic safety circuits of various industrial equipment. Typical applications include emergency stop monitoring, safety door monitoring, and limit switch monitoring.

Q: In which types of equipment is this safety relay primarily used?

A: Due to its high reliability and fail-safe design, this relay is widely used in various stages of industrial production processes, covering manufacturing, chemical, and energy industries. It is an indispensable safety control component in automated production lines.

Q: What exactly does "force-guided contacts" mean?

A: Force-guided contacts are the core safety mechanism of a safety relay; essentially, they are a mechanical linkage structure. They physically and rigidly connect the normally open (NO) and normally closed (NC) contacts inside the relay, thus structurally eliminating the possibility of both closing simultaneously.
