The digital output module has six isolated change-over con-
tacts which can be connected to actuators or other switch-
able devices.
The unit plugs into the XSL514 Terminal Block and can be
inserted and removed without disturbing other units on the
bus. Terminals 1 through 18 are switched according to the
adjacent figure. Six LEDs are located on top of the module.
The module address is set using the rotary HEX switch.
Beginning with V2.04.00 Excel 500 controller firmware, the
online point attribute Normally Open / Normally Closed
(NO/NC) defines the relation between the physical state
(relay on/off) and its logical status. See Table 9.
NOTE:
The digital outputs can be used as status contacts
or as alarm contacts, depending upon how they are
defined in CARE. All outputs from a single module
must be used for the same purpose.

the point attribute NO/NC for the XFL524B.
