The PNOZsigma relays are compact safety relays in widths 22.5mm and 45mm. They are used for monitoring E-STOP, safety gates, light barriers, two-hand controls or ESPEs with safe PNP transistor outputs and contact EDM. The relays are jumper link programmable for either PNP or NPN signals. http://www.pilz.com
They must be connected to a remote RESET device such as a pushbutton station to initiate the reset enabling function. The remote reset can reset the contacts if the pushbutton is held closed for more than 0.5s and can reset both the contacts and the internal relays if the pushbutton is held closed for more than 3s.
The chapter “Technical Description” is the first of several chapters that provide technical details of the PNOZsigma relays. The chapter is an introduction to the PNOZsigma relay range and offers an overview of the product range and the functions that are common to all relays in the range, before giving the variable features of the individual relays in later chapters.
