PILZ PZE3 V22 24VDC Product Introduction
PILZ PZE3 V22 24VDC is a high-performance safety relay module designed for safe voltage monitoring and control in the field of industrial automation.It complies with international safety standards and is widely used in mechanical protection,energy management and process automation systems.
Core Functions and Positioning
Safety Voltage Monitoring
-As a member of the PNOZsigma family,this module can monitor the 24VDC power supply voltage in real time.When the voltage is lower than the preset threshold,the safety circuit is triggered to prevent equipment misoperation or safety hazards caused by power failure.
-Supports voltage threshold adjustment for the food and beverage industry(such as 12V/6V)and general industrial scenarios to meet the requirements of different industry standards.
Safety Locking System(SLS)Core Components
-Integrated LED diagnostic function to quickly locate faults and reduce downtime;work with small controllers(such as PNOZmulti)to ensure a safe voltage-free state during equipment maintenance.
-Meets UL 6420 requirements for SLS applications,simplifying the compliance process in the North American market.
Redundancy and reliability
-Supports redundant configuration(such as 1B1 redundancy),and key components(memory,power supply)can be redundantly designed to improve system stability.
-Adopts electronic solid-state technology,which is wear-resistant and has a long life,and is suitable for high-frequency operation scenarios.
Technical parameters
Electrical characteristics
-Working voltage:24VDC
-Rated current:configured according to the model(such as contact load 24A)
-Protection level:IP20(standard),higher protection version optional
Function expansion
-Supports industrial protocols such as Modbus and PROFIBUS,which is easy to integrate into the SCADA system.
-Integrated diagnostic interface,real-time monitoring of operating status and generation of fault reports.
Application scenarios
Industrial machinery safety
-Used for safety door monitoring,emergency stop buttons,and grating protection systems to meet safety standards such as ISO 13849-1.
-Integrated voltage monitoring function to prevent the risk of accidental power-on of equipment due to main switch failure.
Energy management
-Monitor the voltage status of photovoltaic inverters and battery energy storage systems to ensure safe grid access.
-Suitable for overvoltage/undervoltage protection of charging piles,UPS and other equipment.
