Form A Relay - When the relay is energized, the contacts close, allowing current to flow. A “ form b ” would mean the contacts are normally closed when the coil of the relay is not energized or the there is no magnetic field nearby in a reed switch. Isolation test voltage 5300 vrms. For definitions of compliance please see www.vishay.com/doc?99912. Web a “ form a ” would mean the contacts are normally open when the coil of the relay is not energized or the there is no magnetic field nearby in a reed switch. Web form a relays (or normally open/no relay) have a single set of contacts that are normally open, meaning the circuit is open when the relay is not energized. It can be used with either ac or dc loads (figure 8). Load current 200 ma / 350 ma. It is constructed using a gaalas ired actuation control and mosfets for the switch output. Features • isolation test voltage 3750 vrms • typical ron 19
