Pilz 772170 PNOZ M EF 1MM Safety Expansion Module

Precision Speed and Motion Monitoring

The Pilz 772170 (PNOZ M EF 1MM) is a safety-related expansion module for the PNOZmulti configurable safety system. This module is specifically designed for motion monitoring, including standstill, speed, and direction of rotation. It ensures that dangerous machine parts are only accessible when they have come to a complete stop or are moving at a safe, reduced speed.

Functional Operation

The module interfaces with various encoder types or proximity sensors to track motor movement. Through the PNOZmulti Configurator software, users can define safe speed limits and standstill thresholds. If the monitored parameters exceed the defined limits, the module triggers a failsafe shutdown of the drive system.

Hardware and Safety Standards

• Dual-Channel Monitoring: Features a redundant architecture to meet the highest safety standards (up to PL e and SIL 3).

• Encoder Support: Compatible with TTL, HTL, and Sin/Cos encoders for versatile drive integration.

• Diagnostic Clarity: Integrated LCD or LED status indicators facilitate fast troubleshooting of motion-related faults.

Safety in Modern Manufacturing

The PNOZ M EF 1MM is critical for automated warehouses, woodworking machinery, and any application involving rotating shafts. By providing reliable motion feedback, it prevents accidents and ensures compliance with global safety regulations.
