General Description

The LR4 Latching relay module utilizes latching relays that provide some unique characteristics as outlined:

· Low power consumption: Once the control module changes the state of the relay by applying power to a coil, power can then be removed as the relay mechanically latches its state. Conventional relays require the power to be continuously present to hold a relay in one of its states.

· Relay state is Non-volatile: Once a relay is set to a desired state the relay will remain in that state even if power is lost to the control module. The only way to change the state of a relay is to send a valid command that instructs the relay state to be changed or by using the manual toggle button.
