Solid State Relays

DIN-rail solid-state relays combine electronic switching with convenient control-panel installation. The range includes ultra-slim interface relays for PLC applications as well as higher-power SSRs with integrated heat sinks for direct switching of industrial loads.
Compact SD/SA series interface relays provide AC or DC switching in a slim DIN-rail package, with output ratings up to 8 A DC or 6 A AC. AC versions feature zero-crossing switching, while DC versions provide instantaneous switching.

For applications requiring additional load protection, the SDP/SAP series incorporates electronic protection against conditions such as short circuit, overload, overcurrent and overtemperature, depending on the version. These modules are only 6.5 mm wide and are available up to 10 A for DC loads. Elco Italy

PCB-mounted solid-state relays provide compact, reliable electronic switching for direct integration into control boards and electronic equipment.
Available in multiple footprints, input ranges and AC or DC output configurations, these relays provide electrical isolation between control electronics and switched loads while eliminating the mechanical wear associated with conventional electromechanical relays.
The portfolio includes ultra-slim 5 mm SSR01/SSR02/SSR05 devices as well as higher-current SSR21, SSR22 and SSR30/31 families for applications requiring greater switching capability. Elco Italy
