DESCRIPTION
- Ground fault protection
• Instrumentation
• Industrial controls
The LH1502 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 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.
