Resideo RA889A1001 Switching Relay 322838-754 Fail-Safe Operation: Mechanical spring returnThe Resideo RA889A1001 Switching Relay is a heavy duty solution for intermediate switching of line and low voltage devices in hydronic heating systems. Engineered for 120Vac primary voltage, this relay features a Single Pole Double Throw (SPDT) configuration paired with a PowerPile rated low voltage SPST relay, making it ideal for converting millivolt systems to modern 24V control. The integrated transformer secondary rating of 24Vac provides 9 VA for
