The maximum relay current for the relay board is 5 amps when switching 115 VAC or 220 VAC and 1 amps when
switching 24 VAC .DRY
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 .
