Instrumentation
Industrial controls DESCRIPTION
The LH1505 contains two normally open switches that can
be used as two independent SPST relays or as one DPST
relay. The relay is constructed using a GaAlAs LED for
actuation control and integrated monolithic dies for the
switch outputs. The die, fabricated in a high-voltage
dielectrically isolated technology, is comprised of a
photodiode array, switch control circuity, and DMOS
switches. In addition, the LH1505 relay employs current
limiting circuitry, enabling it to pass lightning surge testing
as per ANSI/TIA-968-B and other regulatory voltage surge
requirements when overvoltage protection is provided.
