Solid state relay board for control of auxiliaries such as engine start/stop and horn effects from the Mtroniks digiSound602 sound module direct from the DCi handset.

The Mtroniks relay board uses solid state technology, meaning no relays! This makes the unit infinitely more reliable and robust than other conventional relay boards, allowing use of auxilliaries up to 15Amps per channel!

The relay board is supplied with a plastic case. The relay board simply slots into one of three possible mounting positions depending on your personal wiring preferences.
