Harmony™ SSL Relays

Harmony SSL solid state relays offer the advantages of several input and output configurations for both AC and DC switching applications. Their compact size and modular design reduces space and allows easy mounting on the socket. Key features include: • Available with zero voltage switching for resistive load and random switching for inductive load applications. • Socket with reverse polarity protection circuit and LED indicator for easy identification of control status.
