By applying DC control voltage, the output semiconductor is activated at the peak of the line voltage. The semiconductor switches OFF, when load current crosses zero, upon removal of the control voltage. The LED indicates when the output is activated. - **Blocking voltage up to 1400 Vp** **• Opto isolation: 4000 VACrms Orderin Ke g y RM 1 C 60 D 50 Solid State Relay Number of poles Switching mode** ~~— "9~~ **Rated operational voltage Control voltage Rated operational current** ## **T e Selection yp** **Switching mode Rated operational voltage** C: Peak Switching 40: 400 VACrms 40: 400 VACrms 60: 600 VACrms **Control voltage** D: 4.25 - 32 VDC **Rated operational current** 25: 25 AACrms 50: 50 AACrms 100: 100 AACrms ## **Selection Guide** |**Rated opera-**|**Blocking**|**Control**|**Rated op er a tion al current**|| |---|---|---|---|---| |**tional voltage**|**voltage **|**voltage **|**25 AACrms 50 AACrms**

Use of mains filters may be necessary for cases where the user must meet E.M.C requirements. The capacitor values given inside the filtering specification tables should be taken only as indications, the filter attenuation will depend on the final application. - The manufacturer has set the maximum allowable deviation under the influence of RFI to +/- 1.0% FSD or +/-1 step in distributed modes. - Control input lines must be installed together to maintain products’ susceptibility to Radio Frequency interference. - Performance Criteria 1: No degradation of performance or loss of function is allowed when the product is operated as intended. - Performance Criteria 2: During the test, degradation of performance or partial loss of function is allowed. However, when the test is complete the product should return operating as intended by itself. - Performance Criteria 3: Temporary loss of function is allowed, provided the function can be restored by manual operation of the controls. **3** Specifications are subject to change without notice (05.08.2025) ## **RM1C** ## **Heatsink Dimensions (load current versus ambient temperature)** ## **RM1C..25** ## **RM1C..50** |**RM1C..25**|**RM1C..25**|||||**RM1C..50**|||| |---|---|---|---|---|---|---|---|---|---| |Thermal resistance
