Technical data

Inputs digital no digital inputs
Outputs digital no digital outputs
Input voltage (sensor supply)

inputs are supplied by ASi or by AUX (24 V or 48 V auxiliary power). If supplied by ASi, inputs shall not be connected to earth or to external potential.

selectable, out of ASi or out of AUX, Default out of ASi
Output voltage (actuator supply)

Electronic outputs are supplied by ASi or by AUX (24 V or 48 V auxiliary 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.

no output voltage
Connection push in terminals
Round cable

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.

no
ASi address

Bihl+Wiedemann offers modules with AB address, single address or ASi-5 address. In some cases, ASi modules can occupy several (different) addresses. Mixed operation of modules with different addressing in the same ASi circuit is permitted.
For ASi modules with two ASi-3 nodes, the second ASi-3 node is turned off as long as the first ASi-3 node is addressed to address "0".
Upon request, ASi modules are available with specific ASi node profiles.
