Fault Tolerant Configuration
For fault tolerant operation, two monitored Guarded output
modules are connected in parallel as shown in Figure 4. In
this configuration, operation continues even if one module
fails.
In the fault tolerant configuration, a failed module can be
removed and replaced without interrupting operation of the
loads.
