Application area of the device

The module BWU2236 is a decentralized output-module that safely controls ac-
tuators on the AS-i Safety at Work (SaW) safety bus system.
In this set-up, a Safety Monitor or a Gateway with integrated Safety Monitor, re-
spectively, controls the BWU2236.
A special characteristic of this module is its three different kinds of AS-i address-
es:
• safety output
BWU2236 listens to the communication on the safe address and switches
based on these data.
• safety input slave
One safety input slave which monitors the two contacts S1 and S2.
• diagnostic slave
The standard AS-i slave (AB slave) is used for diagnostic purposes and for
switching under normal operating conditions.
Attention!
For protective operation of the module the switches must be in the ON/RUN position.
All SaW output modules with the same safe AS-I address switch at the same
time.
