Protective devices for level crossing control systems S111 type, S112 type, S1112 type

拡大

 

The S111 type is used as lightning protection for railroad signal level crossing control systems (HO type) open track circuits. The device is a single, compact protective device (arrester) that has the same performance as the S100 protective devices (for signals) that conventionally exist separately on the DC 26V power supply, on the track and on the relay output.
The S112 type is used as lightning protection for railroad signal level crossing control systems (HC type) closed track circuits. The device is a single, compact protective device (arrester) that has the same performance as the S200 type protective device that conventionally exists separately on the AC 200V, 400Hz power supply side, the S100 type that is used on the track, and the S100 and S200 types that are used on the relay outputs.
The S1112 type is a S112 type protective device (arrester) that has an additional track circuit protection element, making it a four-element unit.
