The Noris RF Limit Value Switches of the series 5 are designed to monitor and process electric measured variables. When the actual value of the measuring signal supplied reaches the setpoint, the built-in relay will operate. The switching status of the relay contact may, for instance, be monitored or individually processed by a machine controller.
