Phoenix Contact's product range of industrial relay systems has been extended to include new relays with bipolarity. They are suitable, among other things, for negative switching applications. They can also be used universally and are compatible with the relay bases from the Rifline complete relay series and the standard PR series.
The individual relays are available in various designs with two or four changeover contacts. They differ in terms of input voltage, limiting current and ambient temperature and are particularly cost-efficient as they do not have a display or input circuit. Silver nickel is used as the contact material, which, in addition to a high erosion resistance, also has a low welding tendency. The mechanical switch position indicator enables the user to quickly determine the switching states. Plug-in modules are available for functional enhancements with LEDs or input circuits.
