Electronic controls for dual-winding solenoid applications. These modules accept your 3-wire switched input (12 or 24V) and apply this input simultaneously to both the solenoid pull-in and hold windings. The relay then removes power from the pull-in coil and leaves only the hold-in coil energized to prevent coil burnout. Trombetta builds three models, which are differentiated simply by the connection type. The S500-A5 has terminal screw connectors and a factory installed jumper (+aux jumpered to +hot). The S500-A6 has terminal screw connectors with no jumper. The S500-A7 has the factory installed jumper along with faston connectors.
