Solid State series relays, at left, have no moving parts. Relay Systems, Inc. has solid state relay models available in most configurations. DC current ratings to over 30 amps and voltage ratings to 200VDC. Solid state relays offer the benefit of no moving parts which eliminates contact related problems. The model shown at left has 2 normally open and 2 normally closed contacts.
