Active Distributors ASi Safety
Active distributors ASi Safety from Bihl+Wiedemann allow you to make any safety sensor, safety push-button or switch AS-Interface capable. Even modules without their own ASi terminal can be easily integrated into an existing ASi network using these active distributors ASi Safety. Other features include individually configurable connection options using M8 or M12 connectors, flying leads or push-in terminals to conform to the customer’s application, as well as a compact form factor, making them ideal for use in cable ducts.
Active Distributors ASi Safety: Input modules
- All Safety I/O Modules: SIL 3, Cat. 4, PLe
- Safety inputs and standard outputs in one module
- Flat design, installation in cable duct possible
- Protection rating IP67
| Figure | Inputs Safety, SIL 3, Cat. 4 | An externally connected relay (contactor) can be monitored by connecting the feedback loop to the EDM input. | Outputs digital | Safety signal inputs | inputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, inputs shall not be connected to earth or to external potential. | Electronic outputs are supplied by ASi or by AUX (auxiliary 24 V power). If supplied by ASi, outputs shall not be connected to earth or to external potential.
For relay outputs the relay contacts are initiated from ASi. The load circuit is powered externally as specified in the data sheet. | PUR line, oil resistant. Further connection options are available on request.
| Under normal conditions (no bus termination or repeater), the permissible total length of the ASi segment is max. 100 m. The calculation should take into consideration that the length of the connection cable (round cable) for each connected passive distributor must be doubled. In the case of the active distributors (ASi modules) however only the one ASi profile cable is counted. | Modules with a flat housing design and with cables which exit the sides make these ideal for installation in cable ducts, cable channels, cable troughs, cable rails or cable trays. Please note the respective housing depth for your particular installation. | Profile cable connection | AB address (max. 62 AB addresses/ASi network), 2 AB addresses (max. 31 modules with 2 AB addresses), Single addresses (max. 31 Single addresses/ASi network), ASi-5 address (max. 62 ASi-5 addresses/ASi network), mixed use allowed. | Special function | Article No. | ||||||||||||||||||||
