  • Compact SIP plastic package
  • Dual output: two relays in one package
  • Normally closed output
  • Low voltage drop

DESCRIPTION

The LPBD100 is a dual-output 100Vdc plastic relay. The relay output-switch contacts are normally closed and will conduct the load current until a voltage is applied to the relay input. With 4 volts or more at the relay input, the output-switch contacts open and the relay no longer conducts. The LPBD100 assembly contains two independent relays, completely isolated from each other, in a single in-line package (SIP). The relays provide optical isolation between input and output terminals. Each relay output circuit uses a pair of depletion-mode MOSFETs for reliable operation.
