Description
Schneider Electric CA2KN40B7 TeSys K Control Relay is used to control a circuit using the signal from another circuit. It acts like a switch that is activated by an electrical signal. 4 NO means that the relay has four normally open (NO) contacts. This means that the contacts are open in the normal state and closed when a control signal is applied.
The relay is designed for voltages up to 690 volts. The 24 VAC coil is the type of coil used in the relay. The coil is the part of the relay that creates the magnetic field necessary to operate the switch. In this case, the coil is powered with 24-volt alternating current (AC).
Schneider Electric CA2KN40B7 TeSys K Control Relay is used in various applications where high voltage circuits must be controlled by a lower voltage control signal.
Features
- It is an electrically operated switch
- It has 4 Normally Opened (NO) contacts
