The Relay block switch the output signal between two values specified in the Output at Switch-on and off point values. If the input signal is greater than the Switch-on threshold value, the relay is on. If the input signal is less than the Switch-off threshold value, the relay is off. When the relay is on, the output signal is maintained to the Switch-on value until the relay is off. Similarly, when the relay is off, the output signal is maintained to the Switch-off value until the relay is on. The Switch-on value must be greater than or equal to the Switch-off value.
