Phoenix Contact PSR Safety Relay Modules

Introduction

The Phoenix Contact PSR Safety Relay Modules are advanced devices designed to enhance safety in various industrial applications. These modules are specifically engineered to monitor the speed of rotating parts, ensuring that safety functions are implemented effectively in machines and systems.

Part Description

The PSR-MM20 relay modules from Phoenix Contact are capable of detecting both overspeed and zero-speed conditions. They evaluate signals from proximity switches to monitor system movement, providing flexible frequency settings up to 31.5Hz (in 0.5Hz increments) or up to 315Hz (in 5Hz increments). These modules comply with stringent safety standards, offering safe motion monitoring up to Category 4/Performance Level e (Cat. 4/PL e) according to EN ISO 13849-1, and up to Safety Integrity Level 3 (SIL 3) in accordance with EN IEC 62061. With features like a 25ms typical release time and an analog output for monitoring speed values, the PSR safety relay modules are ideal for various safety-critical applications.
