Technical data

Inputs Safety

Safe inputs can be configured as 1-channel or 2-channels depending on the desired application or PL and SIL level.


Suitable for applications up to category 4/PLe/SIL 3.

2 x 2 channels, 4 x 1 channel
Safety signal inputs OSSDs, floating contacts
Outputs Safety

Suitable for applications up to category 4/PLe/SIL 3.

no local safe output
Safety signal outputs no Safety signal 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.

out of AUX
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.

out of AUX
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.
