Configurable Digital Output
Module
The configurable digital output
module also has six outputs. Like
the digital output module with the
rotary switch, it is available with
optocoupler and relay outputs.
Unlike the modules with the rotary
switch, however, the outputs are
assigned using a software tool
rather than a selector switch. The
BDA can be used as configuration
software. The outputs can be
assigned the events in the table
opposite using drop-down fields.
The first three module outputs can
be assigned up to six events. All
of these events operate in parallel.
This triggers, for example, a type
of group signal when the circuit
breaker is either impending trip
mode or a phase unbalance
warning is present.
The last three outputs can only be
assigned one of the events directly.
Configuration events include
status signals, warnings, tripped
indication, over/under setpoint
status, waveform buffer triggers,
and the active parameter set.
The module outputs can be set
remotely using communications.
