Active Distributors ASi
Active distributors ASi from Bihl+Wiedemann allow you to make any sensor or actuator AS-Interface capable. Even modules without their own ASi terminal can be easily integrated into an existing ASi network using these active distributors ASi. Other features include individually configurable connection options using M8 or M12 connectors, flying leads or push-in termimals 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, IP67/IP54
- up to 8 cable connections
- round cable/connecting wires
- ASi addressing cable socket
- M8 cable sockets, straight
- M12 cable sockets, straight/angled
| Figure | Inputs digital | Outputs digital | 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.
| Single wiring: 1 input or output per connection.
Y wiring: 2 inputs or outputs per connection.
Mixed wiring: 1 input and 1 output per connection.
Exact pin assignment see data sheet. | 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.
