RMD1H23D20

Hybrid Relay1-Phase Solid State Relay with electromechanical bypass relayType 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 buildingsProduct DescriptionOrdering KeyRMD 1 H 23 D 20The RMD houses semiconductor triacsand mechanical contacts that compliment each other.On applying the control voltage, tri- acs are activated.After a short delay,anelectromechanical relay is activated. This switching method protects the contacts ofthe electromechanical relay and reduces heating of the triacs. The same principle appliesduring removalof the control input. The result is millions of trouble-free cycles in a compact and modular switching package.Hybrid Relay Number of Poles Switching modeRated operational voltageControl voltageRated operational currentType SelectionSwitching mode Rated operational Rated operational Control voltage voltage currentH: Hybrid Switching 23:230 VAC 20: 20AACrmsD: 4-32 VDCA: 24-275VAC/ 24-190VDCSelection GuideRated operationalBlocking Control Rated operational current *voltagevoltage voltage 20 AACrms230 VAC 600 Vp4-32 VDCRMD1H23D2024-275 VACRMD1H23A2024-190 VDC* refer to Current Derating CurveGeneral SpecificationsOperational voltage range 195 - 253 VACrmsBlocking voltage600Vp Zero voltage turn-on<15V Operational frequency range45-65HzPower factor≥ 0.9 @ 230VACrmsSpecifications are subject to change without notice (16.01.2015) 1
