Industrial-Mount DC Solid-State Relays

Opto 22 Industrial-Mount DC Solid-State Relays (SSRs) are designed to deliver isolated DC control and are compatible with low-power Schottky transistor-transistor logic (LS TTL). These relays offer zero-voltage turn-on, zero-current turn-off, 4000V optical isolation, 120V to 575V load voltage ratings, and 3A to 45A load current ratings. The modules are hermetically sealed and feature a unique heat-spreader technology. The rugged, epoxy encapsulation construction is subjected to a full-load test and 6x rated current surge before and after encapsulation. Opto 22 Industrial-Mount DC SSRs operate in a -40°C to +100°C temperature range. These CE components come with a lifetime warranty, as well as UL, CSA, and UKCA approvals.
