[MITSUBISHI ELECTRIC] — UT/UN/UA-SY Operating Coil DC/AC Interface Units
Family ID: MEL-OPT-SY
Mitsubishi Electric SY series DC/AC interface units switch AC-operated MS-T/N/K magnetic contactors and contactor relays directly from DC24V outputs of PLCs and electronic devices. Solid-state (triac, DC24V 15mA input) and relay contact (DC24V 10mA input) output types, in Top ON add-on and separate mounting styles. Operating coils of voltage designation AC100V or AC200V are applicable. UT-SY BC types have wiring-rationalized terminals; UN-SY CX types have CAN terminals. UA-SY types serve the MS-K series SR-K100 relay.
