Reliable monitoring and protectionThe SIRIUS relays by Siemens offer maximum machine andsystem protection and now - with the integration of IO-Link- also communicate with the control level. The new SIRIUS relays for IO-Link monitor network quality, current values,voltages, speed and temperature with proven reliabilitywhile supporting an even broader application area.

Two new device types are offered: ■ SIRIUS 3UG48 for IO-Link: Monitoring of electrical and mechanical parameters ■ SIRIUS 3RS14/3RS15 for IO-Link:Monitoring of temperatures

SIRIUS speaks IO-LinkEnjoy greater flexibility with the SIRIUS monitoring relaysfor IO-Link: In addition to the unchanged autonomous moni-toring function, measured values and data can be directlytransmitted to the control via IO-Link. Also parameterassignment can either be done locally or via IO-Link.Thus, the IO-Link relays are fully integrated in TotallyIntegrated Automation, our open system architecturefor integrated automation.Benefit from considerably simplified device replacement –due to data synchronization and automatic parameterassignment via parameter server.

Your advantages ■Accurate monitoring of electrical, mechanical andtemperature values ■Reliable protection of motors and system components ■Realization of simple autonomous temperature controltasks (2-point, 3-point control) ■Connection to the control level via IO-Link ■Centralized fault diagnostics and localization ■Simplified commissioning and maintenance ■Efficient energy management with SIRIUS 3UG48:Supports data formats defined in the PROFIenergy profile

IO-Link – revolution in the control cabinet

IO-Link facilitates the uniform linking of sensors andswitching devices to the control level – by means ofefficient point-to-point connections. The new commu-nication standard below the field bus level supports central fault diagnostics and localization right down to the sensor/actuator level. Parameter data can bedirectly and dynamically changed in your application.The result: Simplified commissioning and maintenance,increased system availability and reduced engineering effort.
