Description

The LH1502BB relays contain normally open and normally 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 constructed as a mult.- chip hybrid device. Actuation contral is via an Infrared LED. The output switch is a combination of a photodiode array with MOSFET switches and control circuity.
