Internal Relay Wiring (Normally open)
Inductive load management requires a parallel diode for a better contact lifetime.
Warning
The internal relay is limited to a maximum current of 2A @ 30V. If the deadbolt / door strike draws
more than 2A, damage to the device may occur. If the deadbolt / door strike load exceeds 2A, an
external relay must be used.
The internal relay is designed for 100.000 cycles. If more cycles are needed, an external relay
driven by GPO must be used.
