Description
The LH1512 relays contain normally open and nor-
mally closed switches that can be used independently
as a 1 Form A and 1 Form B relay, or when used
together, as a 1 Form C relay. The relays are con-
structed as a mult.- chip hybrid device. Actuation con-
trol is via an Infrared LED. The output switch is a
combination of a photodiode array with MOSFET
switches and control circuity.
