Product Description

The Pilz PZE 5V (Part No. 474956) is a safety relay expander module designed to increase the number of safety contacts and provide timed delays for switching operations in industrial applications. It is particularly useful for applications requiring additional safety contacts beyond the capacity of standard safety relays.
