Siemens 3RK19011GA01 Over Voltage St&ard Rail/Wall Mount Protection Module

The AS-Interface overvoltage protection module protects downstream AS-Interface devices or individual system sections in AS-Interface networks against mains-borne overvoltage that can potentially be caused by switching operations or distant lightning strikes. In the lightning protection zone concept, the overvoltage protection module is located at the transition from zone 1 to 2/3. Direct lightning strikes must be handled by additional protective measures at the transitions from lightning protection zone 0A to 1. The AS-Interface overvoltage protection module can now also be used to integrate AS-Interface in the overall overvoltage protection concept of a plant or machine. The module has the same design and degree of protection (IP67) as the AS-Interface user modules and is also connected in the same way. It is a passive module without AS-I IC and, therefore, does not require its own address in the AS-Interface network. It can be connected to an AS-Interface system via the FK-E or PG-E coupling module. The EEMS interface can be used to protect the AS-Interface cable and auxiliary voltage cable against overvoltage. Overvoltage is discharged via a grounding cable with a green/yellow oil-resistant outer sheath. This cable is fixed permanently in the module and must be connected with low resistance to system ground.
