Latching Relay Board
Latching Relay Board Description
Latching (bistable) relay is a special kind of relay. These are also called "impulse", "keep" or "stay" relays. When the current is switched off, the relay remains in its last state. While a conventional relay uses power continuously when its internal switch is to be closed (relay coil energized), a latching relay require only a brief voltage pulse to change state. The relay will maintain its state when the power supply removed.

A brief (<1s) pulse to Set will close AC terminals, BC will be open
A brief (<1s) pulse to Reset will close BC terminals, AC will be open

  • No power needs to be supplied to maintain its state, ideal for battery applications
  • High quality terminal blocks
  • 5V operating voltage
  • dimension: 77x30mm (PCB size)
  • Set/Reset signal levels:
    • Low level: 0-0.7V
    • High level: >2V
