·EMR/Reed Relay replacement

The Broadcom® ASSR-1611 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 that is 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 5 mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less. The electrical and switching characteristics are specified over the temperature range of –40°C to +85°C.

The ASSR-1611 connection A, as shown in the schematic, allows the relay to switch either AC or DC loads. Connection B, with its advantages of reduced On-Resistance and higher output current, allows the relays to switch DC loads only.
