Product Summary

The ASSR-4128-502E Form A, Solid State Relay consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to a high-voltage output detector circuit. The detector consists of a high-speed photovoltaic diode array and driver circuitry to switch on/off two discrete high voltage MOSFETs. The ASSR-4128-502E turns on (contact closes) with a minimum input current of 3mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less. The ASSR-4128-502E is ideal for: (1)Telecommunication Switching; (2)Data Communications; (3)Industrial Controls; (4)Medical; (5)Security; (6)EMR / Reed Relay Replacement.
