Solid State Relay - DC Control Input/AC Output from Crydom

These industry standard panel mount SSRs utilise a control input between 3 to 32V DC to switch a circuit rated between 24 and 280V AC. They are ideal for use with all of the temperature controllers shown on this website which feature a SSR output. The units are encapsulated in thermally conductive epoxy. We recommend the use of our integral DIN Rail Mounting and Heatsink Kit, which can be mounted on the back of the relay. It gives maximum heat dissipation and allows easy mounting onto a DIN Rail if required. Thermal transfer pads are also available for placing between the relay and the heatsink. The pads can also be used between a relay and the mounting surface when a heat sink is not used. A plastic safety cover is also recommended.
