RELAY; SOLID STATE; 25 AMP

REE-2004 solid-state relays are rugged, optically isolated, single-phase devices with ratings of 10 or 25 amps (with proper heat sinking).These relays accept a DC logic control input and provide precise zero cross fired on-off control in a panel mounted package.Rugged internal snubber circuitry attenuates most industrial noise. The high dv/dt and “blocking voltage“ provide excellent immunity to voltage spikes. A new, fast-responding input circuit allows the REE–2004 to survive high-energy, non-repetitive power-line surges and continue normal operation.Relay status can be seen via the built-in LED status indicator under the clear plastic safety cover.A current-limited DC input (4 to 32 VDC) allows a wider selection of control devices and simplifies integration with PLCs and other externally powered circuits.The REE-2004 relay provides an effective replacement for electromechanical contractors.An excellent application for this relay is switching electric resistance heating elements.The fast switching reduces the thermal cycling of the heating elements resulting in longer element life.In addition, the elimination of mechanical contacts reduces both maintenance costs and downtime.No heat sink is required for loads up to 4 amperes.Loads greater than 4 amps require a heat sink (HPO-4611) and thermal pad (HPO-4612).
