Arico presents ARD 4875 DC-AC 480V relay. It is all solid state with optical coupling for 2500 VAC isolation between an input circuit and an output circuit. Load current is between 10 to 75 A. It can be run by ICs like TTL or CMOS. Snobbier circuit protection is fixed internally. This provides high current application. Device operation status is indicated by LED. The relays provide exceptional dependability and a long working life.
