DESCRIPTION
- On/off hook control
The LH1556 dual 1 form A relays are SPST normally open
switches that can replace electromechanical relays in many
applications. They are constructed using a GaAIAs LED for
actuation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated technology is comprised of a
photodiode array, switch control circuitry, and MOSFET
switches. In addition, the LH1556 SSRs employ
current-limiting circuitry, enabling them to pass lightning
surge testing as per ANSI/TIA-968-B and other regulatory
surge requirements when overvoltage protection is
provided.
- Ring relay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
AGENCY APPROVALS
• UL1577 file no. E52744 system code H, double protection
• CSA certification no. 093751

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
