RMD1H23D20 Carlo Gavazzi

Hybrid Relay 1-Phase Solid State Relay with electromechanical bypass relay Type RMD (for resistive loads) Hybrid relay: Solid State Relay / Electromechanical Relay Operational ratings up to 230V, 20A ACrms Integral bypassing of semiconductors Internal over-temperature protection Compact 17.5mm wide housing Standard modular design DIN rail mounting No need for external heatsink Minimum audible noise Fit and forget: millions of switching cycles Ideal for switching of resistive single phase loads in residential buildings Product Description Ordering Key RMD 1 H 23 D 20 The RMD houses semiconductor the electromechanical relay Hybrid Relay triacs and mechanical contacts and reduces heating of the Number of Poles that compliment each other. On triacs. The same principle Switching mode applying the control voltage, tri- applies during removal of Rated operational voltage acs are activated. After a short the control input. The result Control voltage delay, an electromechanical is millions of trouble-free Rated operational current relay is activated. This switching cycles in a compact and method protects the contacts of modular switching package.
