DESCRIPTION
The LH1501 relays are SPST normally closed switches
(1 form B) that can replace electromechanical relays in many
applications. The relays are constructed as a multi-chip
hybrid device. Actuation control is via an infrared LED. The
output switch is a combination of a photodiode array with
MOSFET switches and control circuity. The relays can be
configured for AC/DC or DC only operation.
