Product Description

The Pilz PZE 9 is a safety-rated, electronic timing relay. It is designed to be a crucial component in the safety circuit of machinery, typically used for monitoring emergency stop (E-Stop) buttons, safety gates, and light curtains.

Its primary function is to reliably and redundantly switch off power to hazardous machine movements when a safety function is triggered. The key features in its name indicate its configuration:

• PZ E 9: Denotes the specific family and function (Electronic Safety Relay).

• 24VDC: Specifies the required operating voltage for the control circuit.

• 8 N/O 1 N/C: Indicates the relay’s safety output contact configuration: 8 Normally Open (N/O) safety contacts and 1 Normally Closed (N/C) auxiliary contact. The multiple N/O contacts are often used to safely disconnect power to multiple actuators or control circuits simultaneously.

Product Parameters

Product Advantages

• High Safety Level: Achieves the highest safety ratings (PL e / SIL 3), making it suitable for applications with severe accident risk.

• High Output Capacity: The generous 8 N/O safety contacts allow a single safety relay to safely interrupt multiple control circuits, reducing the need for additional contactors or relays.

• Electronic Reliability: Being an electronic safety relay, it offers a longer service life and higher availability compared to traditional electromechanical relays.

• Rapid Diagnostics: Incorporates LED indicators and fault monitoring to quickly identify operational status and diagnose trip conditions.

Precautions

• Wiring Principle: The safety inputs must be wired according to a redundant (two-channel) principle (e.g., using two switches) and monitored for short circuits between channels to maintain PL e/SIL 3 integrity.

• Reset Requirement: The module requires a manual or automatic reset after a safety function has been initiated and the condition is cleared. Ensure the reset circuit is properly designed.

• Installation: Must be installed and commissioned by qualified personnel familiar with machine safety standards (ISO 13849-1, IEC 62061) and local regulations.

• Application Limits: This is a single-function relay for E-Stop/safety gate monitoring. It cannot perform complex logic or integrated safety control like a safety PLC (e.g., Pilz PSS or PNOZmulti).

Product Applications

The Pilz PZE 9 is used in virtually all industrial settings where moving machinery poses a risk to personnel:

• Manufacturing and Assembly Lines: Safely monitoring E-Stop circuits throughout the line.

• Robotics: Integrating safety gate monitoring around robotic work cells.

• Packaging Machinery: Monitoring light curtains or safety mats for access protection during operation.

• Machine Tools: Ensuring the safe shutdown of spindles, hydraulics, and pneumatics upon activation of a safety device.
