Series 24 LSR闭锁继电器Series 24 LSR产品介绍：
The electrical power industry has a great variety of requirements for latching type auxiliary
relays to provide maintained contacts -- both N/C and N/O. Often, manually operated switches
are used in conjunction with traditional relays to provide the "maintained" function. However,
traditional protective relays have limitations as to the number of contacts available and their
ability to withstand seismic vibration. Traditional auxiliary relays used in conjunction with the
protective relays also exhibit these limitations.
The LSR Latching Switch Relay was developed to meet these requirements. It is a two position
rotary action Latching Switch Relay that provides control of up to 20 N/O and 20 N/C
contacts in a single device. It is a manually or remotely operated unit used for a variety of
applications; latching relay, reclosing relay, programming relay, and local/remote
switch that is SCADA compatible.

Series 24 LSR闭锁继电器Series 24 LSR产品使用指导：
Contact Deck Arrangement
The blade and terminal configuration enables the use of multiple contacts in the same
deck, and simple stacking procedures enable the fabrication of many independent contacts
in one relay. Specifically, two N/O contacts and two N/C contacts are provided in each
deck, and ten decks can be stacked, resulting in a relay with up to forty contacts. This deck
arrangement is illustrated in Fig 1.
The contacts operate reliably, using every contact and terminal illustrated. For good practice,
however, it is suggested that polarized voltages should not be used on adjacent contacts.
This is because of the remote possibility of flashover during transition between adjacent
contacts -– especially at the higher DC ratings, or in highly inductive circuits.
The illustration of the basic deck LSR layout is for the first deck. For multideck units the second
digit of the terminal number is the same as the deck number.
As an example: Terminal 82 is in the eighth deck, in line under terminal 12 and is a N/O
contact used together with terminal 84.
Contact Ratings
The LSR Latching Switch Relay has been tested to many different circuit conditions. The interrupting
ratings are based on 10,000 operations of life, using suddenly applied and removed
rated voltage, with no extensive burning of contacts. Inductive ratings are based on tests using
standard inductance L = 0.04 for DC and cos θ = 0.4 for AC. The Interrupting Rating column
headed "double contacts" means two contacts in series. Short-time and continuous ratings
are based on temperature rise in contact members and supporting parts not exceeding
50°C above ambient.
