The electromagnetic system of the stepless enhanced contact slow release relay is the same as that of the stepless slow release relay (JWXC-H340). The magnetic circuit system of the JWJXC-H125/80 stepless enhanced contact slow release relay adds a copper short-circuit ring to make the slow release time longer.
The contact system consists of two parts: ordinary contacts and enhanced contacts. The structure of ordinary contacts is the same as that of non-polar relays, and the reinforced contacts are specially designed high-power contacts and arc wave devices.
Product Usage
The transmission relay is one of the important equipment in the AC counting code automatic blocking equipment. The DC pulse sent by the electric code transmitter is transformed into an AC pulse by the relay, and then sent to the track circuit.
JCZC2-2000 transmission relay is used in the station.
Features
Heavy spring force relay.
It is necessary to install a shock absorber when in use.
