●The ASSR-1611 Solid State Relay (SSR) is specifically designed for high current applications, commonly found in industrial equipment. The relay is a solid-state replacement for single-pole, normally-open, (1 Form A) electromechanical relays.
●The ASSR-1611 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 relay turns on (contact closes) with a minimum input current of 5mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less.
●The ASSR-1611 connection A, as shown in the schematic, allows the relay to switch either ac or dc loads.
●The connection B, with its advantages of reduced on-resistance and higher output current, allows the relays to switch dc loads only. The electrical and switching characteristics are specified over the temperature range of -40°C to +85°C.
