ASSR-3211 Overview
The ASSR-32X X S eries c onsists of an AlG aAs infrar ed light-emitting diode (LED) input stage optically coupled to a high-v oltage output det ector circuit. The detector consists of a high-speed phot ovoltaic diode arra y and driver circuitry to switch on/off t wo discrete high v oltage MOSFETs. The relay turns on (contact closes) with a minimum input current of 3mA thr ough the input LED.
