The HSSR-8400 consists of a high-voltage circuit, optically coupled with a Light-Emitting Diode (LED). This device is a solid-state replacement for singlepole, normally-open (1 Form A) electromechanical relays used for general purpose switching of signals and low-power ac/dc loads. The relay turns on (contact closes) with a minimum input current, IF, of 5 mA through the input LED. The relay turns off (contact opens) with an input voltage, VF, of 0.8 V or less. The detector contains a high speed photosensitive FET driver circuit and two high voltage MOSFETs.
This relay's logic-level input con trol and very low typical output on-resistance of 6 W make it suitable for switching of audio frequency signals in telecom applications. Connection A, as shown in the schematic, allows the relay to switch either ac or dc loads. In this configuration, the 150 mA output current rating allows it to switch small loads that are driven from 110 Vac and 220 Vac power lines. Connection B, with the polarity and pin configuration as indicated in the schematic, allows the relay to switch dc loads only. The advantage of Connection B is that the on-resistance is significantly reduced and the output current capability increases by a factor of two.
The electrical and switching characteristics of the HSSR-8400 are specified from -40°C to +85°C.
