Sigma Relays are switching equipment that can control electrical circuits. The primary reason for using relays with an electromechanical system in electrical and electronic circuits is their ability to control high currents with low currents. Relays are generally used in control circuits.

• Level Control Relay: Used in monitoring environments such as tanks, water tanks, and wells containing conductive liquids.

• 1-Phase Voltage Relay: For protection of devices and motors in single-phase systems from over and under voltages

• 3-Phase Voltage Relay: Protecting devices and motors in 3-phase systems from over and under voltage,

• Asymmetrical Cycle Time Relay: General room ventilation, periodic dehumidification, lighting control, circulation pumps, signage, etc. in areas,

• Star-Delta Delayed Time Relay: Provides the required time interval during the transition from star connection to delta connection,

• Single Function Time Relay: Used in applications where the function and time requirements are known.

• Multi-Functional Time Relay: Used in electrical devices, lighting control, heating, motors, pumps and fans (10 functions, 10 time intervals, Multi-voltage).
