The RS Pro RM1D series expands of DC solid state switching solutions up to 100 A for supply voltages up to 60 VDC, up to 50 A for supply voltages of maximum 200 VDC and up to 10 A for supply voltages of maximum 500 VDC. This new range is suitable for panel mounting or for mounting on a heatsink. The switching of the RM1D is controlled by a DC voltage in the range of 4 to 32 V. An LED indicates control voltage presence on the SSR.DC Panel Mount SSR 60VDC 100A 4- 32VDC Control Voltage, with LED indication High switching frequency 1000Hz Clip on IP20 Terminal Cover Self-lifting terminals Isolation input / output: 3750 Vrms Operational voltage : 1 VDC -60 VDC Leakage current @ rated voltage: 0.1 mADC Pickup Voltage: 4 VDC Dropout voltage: 1.2 VDC Response Pickup : <100 Us Operating Temp : -200°C to 800°C (-40°F - 1760°F)
