Trombetta Solenoid Control Modules (S500)

Dual coil solenoids contain a high current pull-in coil and a low current, continuous duty hold-in coil. Once the solenoid has pulled-in it is necessary to disconnect the high current pull-in, winding from the system and leave only the low current hold coil energized to prevent coil burnouts.

Trombetta’s modules allow you to incorporate these dual winding solenoids into applications where they couldn’t be used previously. These modules accept your 2 wire input plus an optional auxiliary control wire, (12V or 24V) and applies this input simultaneously to both the solenoid pull-in and hold windings. After a short period of time (.5 seconds), the module timer/relay removes the power from the pull-in coil and leaves only the hold-in coil energized.

The basic models A5, A6, and A7 are only suited for dual coil solenoids. The models A50, A60, and A70 can control both dual and single coil solenoids.

  • Models A5 and A50 accept a 2-wire (+/-) input; (screw terminal configuration)
  • Models A6 and A60 accept a 2-wire (+/-) input, plus a low current auxiliary control wire; (screw terminal configuration)
  • Models A7 and A70 accept a 2-wire (+/-) input, plus a low current auxiliary control wire; (fast-on configuration)
