Power Intermediate Relays RS Series
Power relays of the RS series are designed for switching both power circuits and control circuits. Their main difference from most similar relays is the presence of a special base that does not allow installing these relays on the board. The use of sockets with an 11-pin round connector allows these relays to be mounted on a DIN rail. Such a block guarantees high reliability of electrical contact and strong fixation of the relay in the mounting block. A special guide in the center of the round base of the relay ensures its error-free orientation when installed in the socket.
The contact group, consisting of three changeover contacts, is designed for a load current of up to 10A (according to AC-1). The RS series relays are ideal for switching loads such as fans, valve coils, circulation pumps, heating elements, etc.
The obvious advantages of the RS series relay include the presence of powerful power contacts, a transparent case that allows you to clearly see the status of the contacts, a bright LED indicating the operation of the relay, as well as full compatibility with relays of this type from other manufacturers (in accordance with GOST 11152-82). First of all, this applies to the Finder relay series 60.13.
The relays of the RS series are rated IP40 on the body side and IP00 on the terminal side.

Unfortunately, the parameter limiting the wide use of these relays is the lack of a wide range of control voltage ratings.
