CROUZET, represented in Australia by ITC Products , has released dual solid-state relays. Each relay has two outputs controlled by two independent inputs. This allows engineers using multiple solid state relays in a panel to save space while maintaining the same number of poles for switching their loads.
The dual SSR=s also use a DBC substrate and bussed power lead-frame. They come with internal transient protection. Two loads can be switched in half the space of a traditional single-phase SSR. Each output is controlled by its own independent input, allowing for individual loads to be powered separately.
Crouzet's dual solid-state relays are rated at 25A or 40A (50A and 80A total) at either 24V-240V ac or 48V-660V ac. They are available with either quarter-inch QC terminals or traditional saddle-clamps. The input connector is either a standard four-pin male terminal or four-pin keyed/locking terminal block.
They mount Crouzet’s standard panel and DIN rail heat sinks. The total package current (both channels combined) must be used when determining the appropriate heat sink for use with a dual solid-state relay.
