• Timing Relays 3RP electronic timing relays are used for all time-delayed switching processes in control, starting, protection and regulating circuits. Siemens wide range of designs means that we have the ideal solution for every customer.

  • SIRIUS 3UG Monitoring Relays The new SIRIUS 3UG Monitoring Relays increase the availability and productivity of your plants and machines. By monitoring the electrical and mechanical quantities, production faults are avoided. Plants are protected from currents that are too high, incorrect phase sequence or overvoltage. The SIRIUS 3UG Monitoring Relays offer freely parameterizable threshold values and functions, a clear diagnosis and they can even correct an incorrect phase sequence independently.

  • Temperature Monitoring Relays 3RS These relays are used to measure temperatures in solid, liquid and gaseous mediums; they evaluate whether the temperature is within the upper and lower temperature limits.

  • Thermistor Motor Protection 3RN1 3RN1 thermistor motor protective relays offer substantial advantages wherever current-dependent protection over circuit-breakers or overload relays is simply not enough: in certain situations overheating may occur, which the thermal mapping in the circuit-breakers/ overload relays is unable to detect.

  • 3TK28 Safety Relays Safety relays are used whenever safe and reliable shutdown is required in dangerous situations. SIRIUS safety relays are essential elements in our system-wide, cost-efficient safety chain. Whether EMERGENCY STOP shutdown, protective door monitoring or optimum protection of presses or punching machines Siemens comprehensive program ranges from economic standard devices to innovative, highly- flexible multifunctional units to cover virtually all applications.

  • Interface converters 3RS17 Interface converters perform the coupling function for analog signals on both the input side and the output side. They are indispensable when processing analog values with electronic controls.
