R.S.Electronics offers linear solidstate relays. This relays do not incorporate any moving part in the load switching circuit and are therefore insensitive to shock and vibration.
In addition, they provide advantages, such as long life, high reliability, no contact arcing, phase-angle control for smooth operation, low electromagnetic interference [emi], high resistance to aggressive chemical and dust, fast switching, no electromechanical noise, logic compatibility, low coupling capacitance, etc.
The relays are available in single and three versions with current capacity of 25, 40 and 50 amp accepting the input of linear 4-20 ma.
