CONTACTS: These relays act as a dry contact switch only and have no connection to the input VAC. The relay ratings
are 5A and 250 VAC.
115 VAC Normally Closed: These relays supply the input voltage to the load when the relay is in the “OFF” mode.
Note that both VAC inputs are controlled by the relay. The relay ratings are 5A and 250 VAC.
115 VAC Normally Open: These relays supply the input voltage to the load when the relay is in the “ON” mode. Note
that both VAC inputs are controlled by the relay. The relay ratings are 5A and 250 VAC.
115 VAC SPDT: These relays are hard-wired selectable to be either NO (Normally Open) or NC (Normally Closed)
switching of the input voltage. They are always powered, and the wiring will dictate whether the power flows in the on
or off position. The relay ratings are 5A and 250 VAC. The neutral is common for both NO and NC.
24 VAC Normally Closed: These relays supply 24 VAC to the load when the relay is in the “OFF” mode. Note that both
VAC inputs are controlled by the relay. The relay ratings are 1A and 250 VAC.
24 VAC Normally Open: These relays supply 24 VAC to the load when the relay is in the “ON” mode. Note that both
VAC inputs are controlled by the relay. The relay ratings are 1A and 250 VAC.
24 VAC SPDT: These relays are hard-wired selectable to be either NO (Normally Open) or NC (Normally Closed)
switching of the 24 VAC. They are always powered, and the wiring will dictate whether the power flows in the on or off
position. The relay ratings are 1A and 250 VAC. The neutral is common for both NO and NC.
