The latching switch relay (LSR) from Electroswitch can be used for latching or reclosing and can also serve as a programming relay for a local or remote SCADA-compatible switch. Designed for use in the electric power industry, it can open, close, and maintain up to 20 contacts (N/O and N/C). The unit's blade-and-terminal design allows for multiple decks and contacts, wo it can be configured for a variety of specific applications. A maximum of 10 decks can be stacked, providing control of up to 40 independent contacts (2 N/O and 2 N/C contacts per dek) in a single device. The LSR is available in two basic models.
