DESCRIPTION
The LH1523 dual 1 form B relays are SPST normally closed
switches 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.
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
